Some wood clothespins make good clamps and you can reverse the wood part on some of them to get a flatter clamp. Make up a few sanding blocks. I use one that's about 3/4" x 3-1/2" x 5-1/2" that has 100 grit on one side and 180 on the other all the time. Keep a shop vac handy and use often. Rubber bands, waxed paper, masking tape. You can get "T" pins in the sewing section of Walmart pretty cheaply. Great kit choice, as mentioned above, Sig will walk you through everything you need and how to do each step. Don't freak out over minor mistakes, your first covering job won't be perfect, but this kit should become a nice flying airplane all the same. Each kit you build will teach you more and turn out a little better.
