As you can see from my picture, I have a lot of plastic shelving units, I live in a 4 bedroom old bungalow style house, the up stairs is totally all sewing, so the plastic shelves start at the beginning of one wall and wrap around to all the walls, one bedroom is now just for my sewing machines, cutting table, corner computer desk, an old pattern filing cabinet, one large wooden cubby with 3 (shoe) cubbies for patterns, thread, zippers, stacks of parts for my purses I make etc. I have my one bedroom up there an then I also have one open concept room about 15 x 20, but the whole hallway both sides of the walls plastic shelving unit next to each other all the way around, my industrial machine, plus 2 aisles of shelving, not to mention 26 gal. totes and boxes an boxes of more stuff, I've been trying to pack up what I don't actually use for now and am putting in basement--which has exceptionally high ceilings because it is an above ground basement which was actually a store at one time, so am trying to organize something down there for the overflow. I still need to get rid of one wooden shelving unit to replace with another table for more of my sewing machines. I'm always creating so yes its always a mess, my son calls me an organized hoarder, because even though I have more fabric than I'll ever use I know exactly where everything is.
