I spent the last 3 days making polymer clay translucent canes, rolling a base, and decorating a cover sheet, and then making these pendants - there are actually 7 of them. However every one has 4 - 6 small hairline cracks on them - mostly on the shoulder edge. I used a method where you put a piece of plastic wrap over the area you want to cut out, and then push down with a cookie cutter. The plastic wrap serves two purposes, one is it stops the cookie cutter from sticking, and second it gives a nice rolled edge to the piece. However I am beginning to think that maybe it also creats stress and thus the cracks. The cracks are not structural, but they bother me - big time! I have 3 left to sand, and I don't know if I want to put the effort into it. If any of you out there in blog land have experience with polymer, can you please chime in and let me know what I have done wrong.
So much for a bit of relaxation during my off time - I guess polymer comes with it's own set of problems. I think I will be back in the glass shop tomorrow.
Have a great week!
