You must be retired. I am and understand the need to be busy. My current "something to piddle with" project is making 1911 grips. Some carved, some with inlays, and some just plain.
Got a couple of "for me" leatherwork projects planned just as soon as I finish a gunstock I'm building and clean up the huge mess I've created with that. Right after I finish the current set of grips I put aside for the gunstock that is.
