Here's what I do. I go to the dollar store and buy the photo albums for $1.00. The I cut a piece of paper the same size as the 'album'. At the top of the paper I write the collection. Example: Oasis (Moda). Then when I make my first purchase I cut the selvage edge that shows the COLOR not the plain white with numbers about 2 inches long. I then go to the website for the manufacturer and look up the collection. I glue or staple the piece of selvage edge to the paper. Under the fabric I put the item number according to the website along with how many yards that I have purchased. I put it in my purse and I know exactly which ones I've purchased and how much yardage. So far I have 3 pages, 6 per page and 1 page with the directions of yardage needed to make the quilt. I always round up 1/4 yard and if I fussy cut, I round up 1 yard. Hope this is clear as mud. It doesn't weigh alot and I always have it on me. Cheryl
