My mom in law just gave me a bunch of old quilt magazines and I read about this but could not make heads or tails of it since I have been learning to quilt the more traditional ways. I do know that the cheaper templates make much easier work with a rotary cutter than cutting out with scissors and paper templates--LOL. Not to mention having to resize pieces because full size patterns were not something they printed.

Oh, I forgot to add, when I use this method, i round the corners because I haven't been able to get a decent sharp point after turning.
