I peel the rubber stamps off the wood blocks they came on. I find it much easier to store them, and use them without the wood attached and getting in the way. =)
I was looking at the last one i took off, and wondering what to do with it:
Then i realized it would make a great drawer knob for the new desk i built. Well its not a new desk, the top is old and salvaged, and the supports are new. One side holds 4 drawers and the other 3 shelves.
