What a stash. Mine is very very tiny compared to that. You must have as much invested in plastic as you have in fabric. I too sew in the basement. I don't mind it as I have the large screen tv down there.
I have plastic that I put other fabric in. I have been trying to keep my projects each in a tub so I keep it all together.
I do keep all my colors together on a shelf. I am running out of room for my stuff. My have to take over more of the rumpus room.
Happy Quilting
