If I hadn't written "polymer clay" in my post title, you would probably be thinking these are stained glass tessarae for mosaics! I've come up with this idea after a long time I'd been wanting to make micro-mosaic jewelry! Regular mosaic tiles are too large for small items such as jewelry, and micro-tiles are in ceramic and hard to find, plus they mostly come in pastel colors... As you know, I love strong color contrasts, so stained glass would be perfect, but it's really hard to cut such tiny pieces as I need!
So I thought about polymer clay! I rolled out thin sheets of polymer clay (my fingers were aching after all the mixing, kneading, conditioning and rolling! If you have a pasta-machine you can devote to your polymer clay work, that would make things easier at least with the rolling out in sheets), then after oven-hardening I just cut the sheets with regular scissors, making tiny pieces (again, lots of work!).
I'm very happy with the result and I can't wait to use my self-made micro-tesserae for my new projects!
