I take pictures of the front and back and some close-ups of the blocks. I have a scrabbook for my quilts, and I put all sorts of things with the pictures--funny sayings related to the quilt theme, pieces of the material, pictures of the people I gave the quilt to with the quilt (like babies on their quilts), and a journalling of my general impression the quilt and my rememberances of making it. I have given away all of my quilts, so this is the best way for me to remember tham.
