Reduce, reuse and recycle. How handy that hubby had some PVC pipe left overs in his studio. He cut them up for me and I used them on these polymer clay bracelets as well as some boxes. Made a whole bunch, but now am out.
I guess not all piping is the same because some will 'melt', some will soften and can be reformed and others aren't affected by baking at all.
To continue making some other types of bracelets, just ordered some great aluminum blanks from Melanie West.
