fraying happens i've learned to live with it. If I don't want it to happen, I wash in the sink, let dry a little and iron it dry. This, of course, doesn't work with yardage.
I had rather clip the mess off the edges rather than take time serger and zig zagging. I do clip corners tho. If I should pink, i get one of the pinking blades for my rotary cutter. Is faster than with pinking shears.
