Okay, but most of my fabric doesn't fray that much. I lose a few lines of threads, maybe a few more on a bad day, but this is essentially helping me to lose all those little triangles.
I made the mistake of using those in my border (thankfully only in 2 spots), and I had to re-sew over the binding 3-4 times because I kept catching the fabric ends but not the inner triangle stuff.
Give me slightly frayed squares over missing fabric any day :D
