I love your shelving unit. Having someplace where you can see your fabric always makes it easier to pick from when you're ready to select fabric for a quilt.
A warning, I was told early on in my quilting life, that if you are storing your fabric on shelves, make sure they are not stained wood but painted shelves. It has something to do with the stain on the wood being absorbed by your fabric and staining it. Paint seals in the wood. If you prefer the wood look, make sure that you line the wood shelves before putting your fabric in it.
