I have made several quilts with upholstery fabrics. Two of them are currently used as throw rugs, two more are on sofas. I recommend sewing with a larger seam allowance, since this fabric seems to fray more easily than quilting cotton. As others said, be sure to pre-wash.
Edited to add: I use corduroy, mixed with flannel, in rag quilts. It frays beautifully. Again, I recommend a larger than usual seam allowance.
