I don't really need to organize anything in my sewing room other than to use up the stash I have. My scraps are in containers by width size, my WOF strips are hanging up so they don't get wrinkled, same for my batting scraps, hanging up by type of batting. I did decided to pull out all my rolling carts under the quilt frame and suck up those nasty little dust bunnies finally plus all the thread tails I didn't get into the trash can, lousy throw I guess. But I finally decided to reorganize my DVD movies upstairs as I have over 1800 movies containing over 2800 disks so a big undertaking on my part. For whatever crazy reason I had back when I had the entertainment built, I started the movies to the right instead of to the left alphabetically plus I pulled out all the Hallmark movies and the series and placed them by themself to the left. Well now everything is alphabetically in order excluding the Hallmark movies starting to the left and moving to the right. I had to put any disk with multiple movies in another area as that's hard to figure out which movie to use to place alphabetically. It took me 2 days but it's done. And yes, I left room for more movies in case I get crazy and order a new one.
My threads in the sewing room are in the same order as their color chart plus I labeled the spindle with the number of the thread color so I know where they go back when finished. My fabrics are organized by color except the batiks as they have their own cabinet and fabrics on bolts are in another cabinet so fairly organized.
