Do you know “Fimo” or “Cernit”? It’ a polymer clay that you can cook in the owen at 110°C. With students of Grade 7-8 can do these small jewels with tools for clay. Laura (11y old) has realized this jewels for her friends but I thought about a School Art Club, to model key rings, earrings, bracelets, lockets and pendants for a charity market. You need a little ‘skill and patience but is very funny realize these small things!
