Cutting 1808 cloth

[berts80]

I'm trying to precut 1808 for my sole. The problem is stretching and fraying. I lay it down on a piece of smooth plywood and put a straight edge on top and run an box cutter knife down the straight edge. After the cloth is cut, I roll it up and unroll on a large flat area. If I try to move it around or handle it in any way it bunches up, distorts, and the edges start to fray. I have not had this problem nearly as bad with 1708. Do I have some bad cloth or is this the way it normally acts. Seems like it's going to be hard to lay one sheet beside the other and keep straight edges.
