I want to thank all of you who shared comments. So many different ways to do it & as usual, it depends on how much work you want to put into it. I really like the idea of the color wheel, & adding the yardages so I know what to buy as fill-ins. Second idea I liked is once I have chosen a pattern, go through the stash, snip the ones I have the right yardage for, then head to the fabric store. Sounds good, but I just can't seem to pass up fabric on sale. lol Somehow, I shall have to put a restraining order on myself!
