Recently, I taught a workshop in which the participants learned to make bracelets without armatures. This requires a few layers of polymer and multiple bakings, but it also is a way to guarantee the resulting bracelet fits the wearer perfectly, and is not going to accidentally come off. We used extruders to create the various designs on the bracelets. The result is a sort of rustic and fun patchwork of shapes and designs. On these two samples, I used a solid color to line the inside. However, it would be possible to use any decorative sheet the artist desires, creating an internal "surprise".
