RE: Cutting out balsa wood parts?
Another thought for the See-Temp semi-clear plastic is your local sewing or quilting shop. They carry this material in various sizes at a very reasonable cost. I talked to one of the sales clerks in a quilting store that my wife goes to and I wound up buying some 36 x 48-inch sheets of the stuff for hardly nothing. She didn't need it any more and it has found a welcome place in my house. One side of the material has a slightly rough texture and you can just lay it over the plans with the rough side up and trace directly onto the plastic. Then, as noted above, just cut it out with scissors or score it lightly and you'll have some superb templates. Lee
