Re the clothespins - I stopped using wooden ones years ago, I had some like you described, but I don't like the idea that the wood can soak up and store impurities (they do discolor after a time). I'm probably overworking that, but that's me. I use plastic clothespins, drill a hole through one side of the finger end to the other, and run a small length of rubber insulating tube (smaller than 1/8th inch) across the two holes, then string them up with the grabbing end down, and oriented like you want them for prints. It takes an hour to do it, but lasts forever.
See the attached. (you can see one of the old wooden ones in the back endm along with some extra tubing)
