Last year the local guild had a show and rented tables/spaces to vendors. Several ladies got together and sold fabrics from their stash. The audience was drawn by the show. The prices they sold their fabric at was cheaper or better than the other vendors there. I purchased a kit, 2 panels and some yardage of a fabric I had been looking for a couple of years. The whole time I was at the show that booth where they were selling fabric was busiest.
Rent a booth at a local quilt show would be my suggestion.
