I have one of those green REI microfiber pack towels. I'd like to bring it on a long-distance tour next summer, but it is huge, and I only really need about a quarter of what I've got. I'm considering cutting off what I need rather than buying a new, smaller one.

My question is whether anyone has done this and how the towel holds up once it's cut. Specifically, does it fray, and if so, how badly?
