I think that getting organized is easier than staying organized. I used to put all my scraps of one color in the same container, but I now have a sandwich baggie for each fabric. I found that it was hard to know how much I had of one fabric.
It is my goal to sew up all my fabric before I die. I have sewn a lot, but still have a lot to go. I try to only buy solid color fabric when on sale. It is my goal not to buy any more fabric until this is sewn up.
Good luck with your stash.
