Great question Bob, and a lot of great answers also. I would definitely stack cut items, this way you get two or three items for the time invested in cutting one. Try to find a cabinet shop where you can get there cut offs, this will help offset your cost of material, sometimes you get lucky and come across some Walnut or Cherry. I would take a variety of things there, and see what sells, that are fairly easy to make, and that you enjoy making. You never know you may end up with someone wanting several of the same thing, ornaments are a good example.
