Another possibility for drapes for your Airstream is Fowler RV Interiors of Symsonia, Kentucky
. Arlene and Henry Fowler are true perfectionists and the quality of their craftsmanship stands the test of time. They created the drapes, upholstery, and refurbished the interiors of both my Overlander and Minuet. I continue to be thrilled with the quality and durability of their work.
