Your room is very nice. I love the window that you have to the right of your sewing machine. If you are like me, sometimes you take a break and look at the view. Like you I have a lot of stuff in a small space.
I too have an issue finding what fabric I want to use. I am wanting to take 1 X 12's and sand and paint them to contrast with the color of my room and use "L" Brackes to mount them just low enough from the ceeling to stand my bolts of fabric on. I still have not come up with a plan for FQ's and fabric not on the bolt.
