When I started quilting, a friend "loaned" me several books of patterns. That was 6 years ago and I still have them. She doesn't quilt anymore and hasn't asked.
In the meantime, just so they don't get lonely, I have every issue of a couple of quilt magazines for the last 5 years or so, plus a few that I just HAD to pick up.
Add to that several patterns for quilts and bags, plus my fabric stash and 2 sewing machines and you get an idea that, "Yes" I belong to a cult!
