When I bought my class C it did not have a good curtain so I made one. Went to Micheal's fabrics and bought a color matching heavy fabric and also a 1/4" foam sheet to line the inside for insulation purposes. I then glued the foam to the back of the material and sewed a hem all the way around the perimeter and added Velcro to attache around the drivers compartment. As a full timer I was looking for good coverage and insulating abilities it works great. FYI I had never sewed anything before I just took my time and used a sewing machine that I borrowed.
