I used to own a quilt shop. I was amazed by people who came in all organized with what they have at home and just need to add to it or with a binder that has all their projects listed out with what fabric they used. One lady would bring in a binder that had every quilt she had ever made having its own sheet. On the sheet would be a picture of the finished quilt, small pictures of each fabric used, where the pattern is found or a copy attached in the binder, too.
Any notes she wrote about the quilt. Pretty amazing. I would like to be that organized, but I would rather be quilting.
