Resin jewelry is slightly more complicated and can be a hassle because it involves mixing chemicals. By trial and error, you can avoid bubbles in the finished product.
Polymer clay jewelry can be created by cutting shapes by hand or using mini cookie cutters, and then assembling the pieces with jump rings. Use a dedicated rolling pin for a more professional result.
Consider how you can use this type of material for purposes other than jewelry, such as holiday decorations such as Christmas ornaments or photo frames.
