I bought the pinking blade for my rotary cutter. It's pricey but so worth it. When I bring home new fabric, I just zip across the cut edges with my pinking blade on my rotary and toss it in the wash. I rarely have anything fray andif it does it is such a small amount I dont worry about it. It's even easier if you have a 2nd rotary cutter for your pinking blade(my 2nd cutter is in a bright zebra pattern so I dont have to check to see which cutter/blade combo I'm grabbing), then you don't have to stop and change it out everytime.
