I have been reading and watching quilting shows for some time. While I have been sewing since I was 8, I realize quilting is a whole new skill. I am interested in using fusible grid interfacing as my first large quilt. Has anyone used it and have any pros and cons they can share. Also what are some of the techniques used to piece it together to make larger quilts. It appears to come in widths o 42", 44" and 45". Any ideas or thoughts are greatly appreciated.
