I carved this Emmett Kelly for a good friend who collects clowns, back in 1998. I used a wonderful dollar store eraser that has since been discontinued. The eraser itself is nearly 3/4" thick and of a very firm, white vinyl material that carves like a dream. I still have a few given to me by another good friend, but I am hoarding those for a special occasion. Now I prefer PZ Kut material as it is closest to this eraser in texture. The only downside is that the PZ Kut is only about 1/4" thick so I get my fingers messy more, but that's a price I'll pay gladly!
