I have my DD old bedroom for my sewing room--I have my cutting dies stashed under the cutting table in the middle, the trundle bed has no 2nd mattress--it holds my "kits" (where I've purchased all the fabric for a specific pattern but haven't touched yet), I have have one of those plastic 5 drawer storage units with the weird, small scraps sorted by color. Then my larger scraps and yardage is sorted by color into an old china cabinet (with the non-glass doors hiding stablizer, etc). I like to make string quilts and have those sorted by dark/lights into huge zip lock bags in the closet and also have all the flannel scraps in the closet. Not super organized but it works. I do go through my fabrics once a year and take those I don't want or seem too small to my guild's garage sale.
