Hello! Can anyone help, i’d like to cut some jewelry pieces from acrylic or cellulose acetate sheets and then finish the edges so they look softer / rounder. I know its possible to do this with sanding but I was wondering if its possible to do it in a rotary tumbler? I have so far gathered I should maybe use ceramic media? If someone could point me in the right direction it would be much appreciated! I’m struggling to find any information online.
