Mine is a bit of mish mash I guess. I try to keep them in color groups but then I keep my batiks together too. Then if I have collections such a the "mirage" blenders from Connecting Threads, etc. I keep them together and the list goes on. I keep all the bolts together too but in color groups. Right now I've ran out of room so its starting to get disorganized again. And we won't talk about the scrap bucket(s) as they're overflowing right now. I keep my scraps by size in shoe box size containers under the cutting table.
