I am in the process of reorganizing my sewing room. I am using white Closetmaid cubeicals. Should I put the fabric in ziploc bags or will it be fine just sitting on the shelf? I would prefer to just leave it on the shelf, it's easier to see for me that way, I think. Now that we're all moved into the new place, I actually have 2 sewing rooms--one for cutting and scrapbooking and the other for my machines and sewing. So I'm trying to get everything organized a little better. Thanks
