I like to have the actual book to write in and attach pictures of the progress and finished quilt. Flipping through the memories is a pleasent past time and the notes I keep help me with future projects.
I use looseleaf binders w/ plastic paper protectors to keep my quilting records.
Copy of pattern
List of fabric
Date start: Finished top: Quilted
Quilt name (not pattern name)
any changes of the pattern I make
Some times I rewrite parts of the pattern to make it easier to understand for me
piecing/ quilting thread
Size and type of Batting
I add samples of the fabrics and write selvage info and cost if I have it
When finished I record who I gave it to and what occassion and date and any back story that might enrich the story of the quilt.
