The author took some old toys, gave them a coat of paint and put a bolt thru them to make drawer pulls. Neat idea but a few changes I would make to this would be: I would have a spacer (small pipe maybe) for the bolt so you don’t need to use a nut to space out the handle, I think I would use superglue over gorilla glue just in case it expanded too much.
