Painting / Finishing Racks
Several people have asked about finishing small pieces like those for puzzles and how to hold them while drying. Here is what I did. I took scrap and and my pin gun and started zapping. The pins are so small they leave almost no detectable mark. And, if you want, you can slightly bend down the ones you do not need or want touching your work. For storage I simply flip two pieces facing each other and pile them up.
For larger, heavier pieces I use the painting pyramids available for woodworking shops and big box stores.
