I keep a three ring binder. When I started about 3 years ago I had ideas for a number of quilts right away. I am lucky perhaps that I still like them and they are still all in the list. I record which sizes for each and which fabric to use for backing and binding. I keep track of the number of blocks I have finished which has been most helpful as I have sometimes stopped work on any item for as long as a year. Several of mine have been worked out from pictures without a pattern so all the information on sizes and pieces is on the first page. I have pages in the back for quilting patterns, ideas for future projects, etc. I really enjoy it and often add to it. It has been very helpful to have.
