If it's good quality fabric it shouldn't fray too much. Just make sure to clip any tangled threads before putting in dryer. I pre-wash everything & usually it doesn't fray too much if it's nice LQS fabric. I am thinking of asking Santa for one of those pinking blades for my rotary cutter, but so far I've been fine with just clipping and frayed threads before drying so you shouldn't really need luck.
