Hambiskit---I'm Cool Even us old guys get pissed off sometimes. One of the best tools I ever bought was my cheapo glue gun. I just hate cutting up good material, only to find that I screwed up the pattern and wasted a sheet of "Unobtainium". On anything that is going to require a trick pattern, I make a rough undersized pattern out of cheap plywood or particleboard, dummy it into position, then cut approximate 1" x 2" peices of construction cardboard and glue them to the undersize pattern, with the 2" edge against whatever the pattern is for. In a tight radius situation, I put the 1" side against what I am patterning. The hot melt glue dries almost instantly, and gives me a perfect "on size" pattern.
