The Sanding Taco is a great idea and you will find a lot of uses for it. Basically it's a stout piece of foam covered completely with Velcro. It's designed to be wrapped with a 5-inch sanding disc and your choice of grit, but I use mine also with a 3-inch disc down at the end. The "folded" part is about 1/4-inch wide and it's great for sanding coves and getting around the foot of a bowl. You can use the curved part on the inside turn of bowls while spinning on the lathe. No more burned fingers!
