Being that I have a dog, two cats, and three kids, I like to keep my fabric in clear storage according to color! This keeps the kids and the animals out of it!
Since I don't have a sewing room I store fabric containers in my closet like most people store shoes! lol Maybe thats why I only have three pair of shoes, tenis shoes, flip flops, and dress shoes! Doing it this way also keeps the sunlight off of it!
I don't know about the design wall!
