I found the Piping Hot Binding Tool! It was in the tub that I took to my friend's house, along with the small sample I make using the tool when I took a class from Susan Cleveland, way back when she was at Lake Farmpark. Go figure!
Now I have to call my friend and explain why I didn't think to look for the tub before I called her. Do you think I can get away with saying that I just wanted to say "hi?"
