She (Susan Cleveland) is a lot of fun and not afraid to laugh at herself. We're fortunate here in that she is a member of our guild. She used to teach at a local quilt shop; then the shop went out of business (definitely not because of her :) and she became better-known and started teaching all over the country. She hasn't taught much locally the last few years. I was fortunate enough to take a couple classes from her when she was teaching locally.
I do quite a few charity quilts and don't use it on those. I've also not tackled piping on a bed-size quilt. I do use it on wall-hangings.
