I have some wonderful cabinets to put my fabrics in Pieces larger than 4-5 yards are stored in one cabinet, Florals/Asian, in another, batiks are separate. Christmas fabrics are together as well as fall fabrics. The childrens prints and animal and military fabrics are separate. FQ's are in drawers and the rest pretty much is sorted by color. I fold my 3 + yards over a 6" ruler and the 1/2 yd to 2 1/2 yard are folded about 4" wide. So I know at a glance If there is enough for borders etc. I do keep coordinated fabrics together if I am planning on using them together. I do have some (about 8 totes) "overflow" fabrics. Most of those are really large pieces. Oh, and all the flannel is separate from the rest.
