I guess I'm really an unplanned sort of quilter. I got one, thinking I'd organize myself, but I soon went far off the rails. I had been using a little spiral bound notebook and wrote down details about every quilt I was working on - when I started/finished, what fabrics & techniques I used, sizes along the way, etc. My log was more free-form than the planner. I found the planner too structured for my needs and went back to the little notebook. Works for me and less expensive. I kept the planner because there are some nice scrap quilt patterns at the back which I look at occasionally. Have yet to make one of the patterns, though.
