Wash before cutting as the edges get pretty frayed after washing. As for cutting, the easiest way is to go to JoAnns fabrics, or some other place that sells fabric, like WalMart, and buy a Rotary fabric cutter, and the cutting mat that goes with it. The mat is marked in inches. You can cut 4-5 layers at a time. Just lay your ticking out on the mat, use a good straight edge,(they sell those at the store too that are clear and marked in inches) and cut long strips. Then you can either use it like that, after lubing it, and cut at the muzzle, or just cut it into squares.
