I store my scraps in those storage containers you can buy at JoAnns that connect together - 3 to a stack with only one lid - I put the 1.5" ones standing up, the 2.0" and 2.5" ones stack up - I put a label on the outside of them with the size so I can tell at a glance what's inside. When I am ready to make blocks, I take out coffee filters and lay about 10 of them out in a row. I take my scraps and deal them like cards so each coffee filter has one of each different scrap in it. That way all the blocks I make when I take a filter to the sewing machine are different with no duplicate fabrics. It doesn't matter that the same material will be in the next filter's worth of blocks because they will be in a different order. Hope this makes sense. I also trim my HST's to those sizes and store those in the boxes too - they can be that 'little surprise' in a block that can make scrappys more fun. I have gotten to the point in my stash that I really don't have yardage - anything bigger than these sizes are stored by color in plastic bins about the size of shoe boxes. I LOVE SCRAPPY QUILTS and am completely hooked on making them. There are always two or three of them going in my sewing room. But, be watchful - they do tend to have babies when you aren't looking!
