The fabrics I've seen that are used for outdoors have been so expensive. Is there an alternative that may be a bit cheaper than the $40 a yard fabric that I've seen so far?
I don't know about that. You could try a place that sells it by the bolt. It would be expensive, but it would be cheaper than buying by the yard. Try online sources.
Do they still have carpet and fabric outlets in Georgia? We went to Georgia and bought our carpet and it was tons cheaper, even though we had to make that long trip.
