Pocket Dress

I love pockets! I once saw a wedding dress on television with hidden side pockets and wished I had seen something like that in time for my own wedding. I think it's because I never know quite what to do with my hands and they always tend gravitate towards pockets (my own, of course). I'm quite proud of this dress which was created by only loosely following the guidelines for the cotton tunic.

I added pockets, long sleeves, darts, and a zipper in the back which weren't in the original instructions. I bought the fabric at a 40% discount sale during Fabricland's 43rd birthday celebration and promptly got started on the dress right after I finished my cotton one. The fabric was more difficult to work with than I had expected because there was absolutely no stretch to it. Consequently I had to put in the darts and invisible zipper so I could easily get into and out of the dress without needing to call for help (which I did the first time!).

Cotton Tunic

At the end of March I developed some crazy allergic reaction and my hands flared up so horribly I missed more than a week of work. It was very upsetting being unable to do anything for myself because both my hands were blistered and swollen over. I only got relief two weeks later when we headed to the emergency room at Toronto Western and they prescribed me with Prednisone. It's been a slow recovery so far, and unfortunately I had to drop my jewellery course at George Brown midway through the term, just as I was about to finish my silver box project (grr).

So, as my hands continue to slowly improve I've decided to temporarily set aside my jewellery tools and bring out the ol' Singer again. Sewing is much kinder on the hands than jewellery-making. Plus I have a few projects lined up already, starting with this cotton tunic/dress. Originally I had longer sleeves and a longer hem line but I started wondering if it was looking to 'granny-style conservative' so I snipped off a few inches. It instantly made the outfit look better.

Gem Setting

The first-level Gem Setting course was offered at George Brown during the winter term and I took it over seven Saturdays for six hours each day. It was by far the most expensive jewellery course offered at the college and I had to purchase a number of tools that cost extra from the tuition. Overall I was very disappointed with the experience and definitely think that it should have been more hands-on for the 42 hours that were invested in it. Despite that feeling I wanted to post the projects I completed anyway since I've been doing so for all of my other courses. 


The rings we worked with were silver cast rings which were tumbled and had a rough finish.  These were provided to us by the instructor. The course focused strictly on the gem-setting technique and we weren't supposed to "waste time" finishing off the rings but I thought it would actually be a waste not to finish them once the cubic zirconia stones were set (which is the hard part). Since there was extra time during each class I went ahead and filed and polished the first three projects after setting the stone.

1.  Four-Claw Setting
We started with the four-claw setting which taught us to use high-speed steel burs, triangle files, and pumice wheels. It was a little unnerving trying to make bearing cuts into the silver claws to match the shape of the stone and secure it in place. The contact surface was extremely small between the bur and the claws. Several times as the bur was spinning it skid across the claw and nearly wrapped around my thumb - yikes! That would have been messy.


I also had a difficult time getting used to wearing the optivisor and eventually just used the lowest magnification available (1.5x) so that I wouldn't get disoriented every time I looked up from my bench pin to reach for a tool.


2.  Bezel Setting



For our second ring we learned about the bezel setting which I found to be easier than the four-claw. We still needed to use the high-speed steel bur but cutting a groove along the inner wall of the bezel was not nearly as daunting as trying to cut out even grooves in the four separate claws. There was a lot of hammering with this ring to displace the metal along the top of the setting which clamped the stone into place. I didn't mind all of that tapping though, probably because it felt like nothing compared to the intense hammering from my silversmith course with my copper bowls!



3.  Channel Setting
For the channel setting we used 156C Tungsten burs to cut out grooves in the channel wall. The spacing between the teeth of the 156C burs is tighter than the spacing for the high-speed steel ones which makes them less aggressive to use. This ring had only five stones but took me a few hours to set because of my inexperience.

After setting all of the stones into the silver ring by hand, we learned the technique of setting stones into wax. I didn't realized that rings could be cast with stones already in them but we learned that rubies, cubics, and blue sapphires are hard enough to withstand the heat from the casting process. Setting these stones into the wax ring gave us a direct comparison between the two techniques. Hand-setting took several hours (for an amateur like myself)...setting in wax took less than 10 minutes! Unfortunately not every design can be set in wax which is why the skill of gem-setting is still important.

4.  Gypsy or Flush Setting
Our last project was the gypsy setting with 13 small cubics. Needless to say this took some time to complete! Again it took me several hours to set in metal but only 15 minutes to do in wax. I didn't get a chance to polish this ring so it still has the brushed metal finish to it.











After completing this fourth project I do not feel at all prepared to try even a simple setting on my own at home. It's not that I expected to be a master gem-setter after only 6 weeks of courses but I thought the course was poorly taught and poorly organized.  I would not recommend it to anyone (and I'll leave it at that!)

Lost Wax Casting: Koi Cuff Bracelet (cont'd)

Here is my finished bracelet after polishing with Tripoli.   I'm really proud of this bracelet which probably took around 30 hours to carve in wax and another 4 hours to finish in metal.  Too bad it's quite heavy and not at all comfortable to wear!  It looks great on my jewellery stand though and turned out better than I ever would have thought.  I will just have to make my second bracelet even better (after a little break in between, of course).

Lost Wax Casting: Koi Cuff Bracelet (cont'd)

I was able to cast my koi cuff braclet in sterling silver this week - how exciting! In my previous class I soldered a massive sprue at the base of the bracelet and then set the mold. I ended up keeping most of the bridge as support so there will be a considerable amount of silver I can recover from this casting. One of my classmates took a final photo of the wax piece just before I said goodbye to it for good.

Preparing the piece for casting
 There was a fair bit of prep before the actual casting process took place. I had a bar of fine silver that had to be cut with copper to make sterling silver which is harder and more durable. It took a painfully long time to melt down such a large amount of silver and my hand was pretty crisp from holding the torch.

Here I am with my instructor Shao getting ready to melt the sterling silver beads with the torch.  In the right photo I'm adjusting the flame before pointing it down into the centrifuge.


After the piece was cast I had to wait another 20 minutes for it to cool down before plunging it in a bucket of water and retrieving the bracelet. That felt like a verrrry long 20 minutes.  Here is the bracelet with the massive sprue sawed off (which took an hour with a tiny jewellery's hand saw!).

Copper Spoon: Forging Technique (complete)

(cont'd from here) Voila - the final product! I might have used the wrong type of planishing hammer the first time I was finishing the surface of the spoon but it created a pretty neat texture on one side. While shaping the bowl I used a different planishing hammer which took out the initial rougher marks. However I decided to keep the texture along the handle because the contrast was more interesting.

Lost Wax Casting: Koi Cuff Bracelet (cont'd)

I was able to dedicate a lot of carving time to this bracelet over the holiday season (I love that my office shuts down for Christmas!).  The bracelet is coming along nicely and I've spent many hours carving, digging, and scraping away wax.  I'm still pretty timid with the tools so I end up making multiple passes over the entire bracelet, slightly deepening the grooves each time.  Not very efficient but I'm getting good practice, that's for sure.
The right-side koi is beginning to take shape

Another 3 hours spent adding details such as scales and fins

The wax model is almost ready for casting. I've spent a considerable amount of time hollowing it out and taking down the thinnest sections of the bracelet to about 1.2 - 1.5 mm. Before the holidays the wax model weighed 33 grams. Now it weighs 15 grams, and will be even lighter once I cut out the bridge and create the opening in the bracelet for my wrist. The weight in sterling silver is approximately 10.4 x the weight in wax so there is definite incentive to get this piece lighter.



In the right-hand photo you can see the neat texture that my instructor suggested I add to the inside of the bracelet. It took about 45 minutes just to do that detail alone but it really gives the bracelet a nice finished look without requiring me to file the finished piece from the inside.

Boxing Day Shirt


I managed to find some time over the Christmas holidays amidst the food and festivities to return to my Singer for a cute little project. On Boxing Day I happily spent the day in my pyjamas at home coming up with the design for this new top. 

Because I had no plans to leave the condo I rummaged around for random pieces of fabric and notions and rediscovered some green and red binding in my sewing box. I spent a few hours hand-stitching the roses and flower stems on the front and back of this top, then assembled the two halves using the Singer. After trying on the top I decided it looked a bit too boxy for my liking so I added white ribbon all the way around the upper portion to break up the blank space. Next came a few red buttons for detail and red binding to tie up the back. Voila!

Lost Wax Casting: Koi Cuff Bracelet


In my model-making class last week I started a cuff bracelet which will probably take me into the new year. This project will give me something to do during the Christmas break when we're off for a few weeks. I was inspired by a design I saw online here. Pretty ambitious I know, but hey it's something to strive for.

After sawing out a thick block of wax for the cuff bracelet I used the drill press to take out the middle section. I drilled a series of holes around the inner diameter and then cut through the remaining bits of wax with a regular jewellery's saw frame. Then it was time to file, file, file!

For now I'm keeping the cuff quite thick to provide support until all of the design has been carved into the front.  After that it can be hollowed out from the inside to reduce the cost and weight of casting.

Design for new bracelet
Here is the design I plan to use for the bracelet.  I found a nice stencil for a single koi online so I simply mirrored the image and added some more flowers as filler. I sized the design for my bracelet, printed it, and  taped it to the wax cuff for transfering. Using a pin I transferred most of the design onto the wax, leaving out the more intricate details such as the fish scales and the smaller flowers. This took about an hour.


Design transferred to wax using pin-pricks

It took me about 3 hours with the flex-shaft and a set of burs to create a sunken relief for the blackspace in my bracelet (I was way too timid with the burs). The instructor thought this project would take 40 - 50 hours to complete - so far I've put in 7 hours. I'll have to decide just how much fine detail I want in this bracelet but ultimately the plan is to have it ready for casting in January before my courses end.

Lost Wax Casting: Dragonfly Pendant




For my next pendant project I decided to try a dragonfly and aimed to make it thinner and lighter than the swan.  I started with a 2mm-thick piece of wax and filed it down to 1.7mm.  Then I used needle files to start forming the overall shape of the dragonfly and borrowed a graver from the instructor to do the grooves in between the wings and beads of the body.


Here it is after I finished casting it in sterling silver.  Again the white colour is from the fine silver which  hasn't been polished off yet.  I made a rubber mold of this pendant after soldering on jump rings and polishing it down a bit.  This time it was alot more difficult to cut the two halves apart in the same plane where the pendant was because the dragonfly is much thinner than the previous swan pendant!



I ended up giving this necklace to my friend and then cast one of the blue duplicates for myself.  I tried finishing the pendants with the polishing wheel to get a high-shine coating but was unsuccessful.  Because the pendant is so thin it heated up very quickly with friction.  This softened the metal (making it easy to bend) and meant it was very difficult  to hold onto the pieces for more than a second or two at a time - hot hot hot!  Eventually I settled for using a tiny polishing wheel with my handpiece.  It couldn't do the job as well as a polishing wheel but saved me from getting any more burns on my fingers!

Copper Spoon: Forging Technique (cont'd)


copper blank and brass template
I did it, I managed to saw out the copper blank in just over 40 minutes and I'm proud to say I didn't break a single saw blade. After filing down the edges and annealing the copper I went on to saw out a brass spoon template. This took about 10 - 15 minutes which seemed like a breeze compared to the 3mm thick copper.




Results after initial forging
Next it was time to tackle the forging hammer. Which really meant pounding for a good 20 minutes and then switching to a lighter hammer. My forearms were throbbing at that point and I figured I was better off having to pound harder with a lighter hammer than having my forearms scream at me for the next two hours.


I had a very difficult time forming the copper blank into the shape of the brass template. The goal was to thin out the spoon bowl and top end of the handle, meanwhile shifting the excess copper into the neck of the spoon where it should be thickest. Shifting metal is easier said than done!

Trying to shift metal from the bowl to the neck of spoon


As you can probably make out in the photos the bowl of the spoon is still quite thick so I have a long way to go. We had the option of also making the spoon out of silver, which only one student chose to do. I wasn't quite confident enough to lay down $80 for a silver spoon but unfortunately that means not being able to use this copper spoon once I'm finished.

Copper Spoon: Forging Technique

For our final project we forged a copper spoon out of this 3mm thick piece of copper. After I was thoroughly exhausted from finishing the second copper bowl, I took one look at this thick piece of copper and decided to leave it for the start of the next class. The instructor estimated that using a jeweller's hand saw and size 8 blades it should take us *only* 45 minutes to cut out the initial shape of the spoon. At that point I called it a night.

3mm thick piece of copper - ugh!

Cloisonne Pendant (cont'd)

Progressing slowly on the pendant. For the background I wet-packed two layers of Grass Green for shadowing and then added a layer of Peppermint Green which needs a second or third coating. The butterfly wings have two layers of Rose Pink but the colour isn't as bright as I expected. I also added a layer of Perriwinkle in the tips of the wings but after firing it seems to have blended with the pink. The body has an opaque yellow until I can think of what else to do with it.

Pendant after two layers
Almost done. I wet-packed several more layers into the cloisonne and the colours are becoming more vibrant. The cloisonne was beginning to curve from all of the firings so the instructor helped me flatten the piece by heating it up and then smashing it flat between two heavy metal plates immediately after removing it from the kiln. It didn't seem like a very sophisticated technique but was very effective. I was skeptical that the enamel wouldn't just crack off. In fact, it would have if we had smashed it even 5 seconds later and the piece had cooled down too much. 


After the cloisonne was flat it was easy to stone, which involves scrubbing it under running water with a piece of carborundum (silicon carbide). This removed excess enamel that was covering the cloisonne wire so now the butterfly outline looks like it is glowing. The cloisonne will undergo one last firing to maturity next week.

Agate Pendant


Ok change of plans. I had originally envisioned making some stud earrings for myself but decided at the last minute to make a pendant instead. The instructor cautioned that if I went with studs it would be very easy to break off the earring posts when I went to set the stones. Since you can't apply heat to metal after setting stones, I wouldn't have been able to re-solder the posts back on or do a whole lot with my finished cabochon settings if I had been so unfortunate.

I decided to switch gears and make a pendant using my two settings. If I had planned this properly I would have selected different sized stones, or different stones altogether, just to make it more interesting.  In the end


Here is the agate pendant with the cabochons set. Finishing this piece off proved to be much more frustrating and challenging than I had thought. The truly frustrating part was keeping the pendant fixed using the waxy resin. The problem was that the resin was considerably contaminated from being used in previous classes so it did a very poor job of holding the pieces in place while I set the stones.


After about the twelfth time of it coming loose (and having made little progress on setting the stones) the instructor gave me a pitch pot of which there was only one for the whole class. The tar in the pitch pot was unbelievably  more effective in securing the settings than the resin and I was able to complete my pendant with far less cursing!

Agate Earrings

After finishing up with the silver band ring I started on my final project in the Jewellery I course. We were learning about cabochons and bezel settings for our next ring project but I was leaning towards making a pair of stud earrings instead.  Here are the Botswana Agate cabochons I picked up along Queen street. In this photo I just finished hammering out the walls of the bezel setting using the bezel mandrel.
