Watch the Class

30 minutes

Make It Yours

5 minutes

Experiment with different hole shapes and patterns on the inner gear to make your own unique spiral art!

I’ve found that curved shapes work better than straight-sided ones. Asymmetric shapes can produce some cool effects—go nuts!

3

Carve It

16 minutes

I’ve tried it in both baltic birch plywood and expanded PVC and they both work. Acrylic would be ideal, but you would probably have to remove the tabs and use double-sided tape.
