As we move along, just a note on a couple of additional tools that I have found very useful. The mini straight edge I use almost exclusively now for medium and short cuts and great for scoring. The handle keeps pieces of fingers from coming off with the paper, the width allows additional and even pressure to be applied along the full length of cut. One side beveled, the other flat...can be used as an assist in folding. The other dandy item is a toolmakers angle plate. Good for placing in tight corners and holding your exact 90 degree angle as the glue sets.
