I sorta feel like the 5th Doctor when the sonic screwdriver got blasted -- "It's like I've lost an old friend!" It was just a little gray lump of clay, inherited from laurie_robey many years ago when I was working on the original NeverNever strips, but there was a lot of art tied up with that little gray lump.
Farewell, kneaded eraser! I hope you find a good home. But now I need to go over to the art supply store.
