I use 2 of the sweater unit hanging closets for my fabric and in some of the cubbies, I have purchased drawers for them, great for patterns.
I also use a shoe hanger which has 10 shelves for my PPing scraps. I have plastic containers like the ones used by manufacturing companies for vacuum packed cold cuts..each shelf hole two containers.......so easy to find and it's all out of the way when not in use.
