My old resin jewellery was made in beer bottle caps. This year I thought that was a bit tacky, so I actually bought some pendant backs to use. Plus, this time I wasn't drunk while making them.
I bought my supplies off etsy.com. It's such a good place to buy supplies! I bought three sets of pendant backs from them. 20 square ones with a loop, 10 thin round ones and 10 thin oval ones. I also bought "one container of watch innards", which looked big in the picture on etsy but is actually microscopic. Charles said I should've bought huge clock parts. Anyhow, they work well.
These ones are made with pictures from old storybooks and other bits of paper. Don't worry, I didn't use storybooks that were any good to anyone.
The ones with clock parts. The background paper is just coffee-stained printer paper. I tried to arrange the clock parts in an aesthetically pleasing manner, but they are so SMALL! It was really hard to get them in the right place without sticking to my hands.
