I have a couple full size profiles cut out of hardboard paneling, but I much prefer clear acrylic so I can see the grain structure in the blank through the pattern, and I only make the pattern from the lock to the buttplate. I have had no issues with chipping, cracking or breaking. I drill a 3/8" hole through the lock end so I can hang all my patterns on the same nail. My bandsaw cuts the acrylic cleanly, and for the purposes of laying out a stock, they are plenty smooth and straight enough.
