Between "real" jobs, once a long time ago, I worked briefly in a factory that produced men's suits. We used a spray on glue to hold patterns on the stacks of material when we cut pant and jacket parts. What was nice about the glue was that it had a very low tack and it didn't leave any residue on the material. The patterns peeled off easily and were able to be used again without adding more glue. If I could remember exactly what we used and could find it, it would be perfect for cutting airplane parts. Anybody ever heard of this stuff? I think it actually said something about "pattern glue" on the can, but I don't recall for sure as this was nearly twenty years ago.
