If the scraps are from a kit or say a set of fabrics I pulled from my stash for a project, I'll keep them together until that project is completely done in case I still need some or if I decide to make a pillow or pillowcase to go with the quilt, then I can pull from the same fabrics and don't have to go searching for them in the many containers they might be in. Otherwise, I'll try to put them in the correct container then just to get them out of the way. Lately though I've been throwing them under the cutting table and then finally when I can't stand it any longer, I'll pull all the loose scraps out and put them where they belong. I've been getting so lazy lately. Plus my scrap containers are overflowing too so I hate to try to stuff even more into them.
