I love to scrapbook so I'll be keeping a scrapbook of all my quilts (hark at her, only finished 1 quilt top so far, getting a bit ahead of myself I think :D )
I have taken photos at different stages of completion (mainly so I can check order of blocks incase I get 'helped' by DS1 & 2 :-o ) and kept notes of how long it has taken me and swatches of fabric etc
