If you’re interested in natural ivory alternatives that don’t smell like fiberglass when sanded, perhaps look into tagua nut, also called corozo. It’s sometimes termed “vegetable ivory” due to its similarity in texture and density to animal ivory. It’s fairly cheap to source from the likes of eBay in rough-cut slices and machines very well on a Nomad.
One of the traditional uses for tagua is to make apparel buttons. The only downside to it is that the nuts themselves only get so large, and there’s a natural void in the center of each one that one must work around. Still, you can get some quite good results from them.
