At the end of last summer, I purchased two bolts of Sunbrella at a garage sale. I just looked at it and I would say it would be OK if you didn't do an intricate design. Any topstitching or quilting should be done with UV resistant thread. You can find it at big box stores. Also, it ravels a bit, might want to consider a wider seam allowance, or shorter stitches.
