I put date started, date finished, type of fabric, batting, etc.
I also leave the bottom half of the page blank for any notes, stories, etc about the quilt. I love going back and reading these!
I also put a picture of the quilt and a small swatch of the fabrics. A few pics of me making it, sometimes.
Here's a good link about them:
