awning material

Has anyone made a lightweight awning for their camper? If so what did you use and where did you get the material? I'm thinking tent material ns attack to trailer by way of snaps and tent poles on outboard side but as yet to find where I could buy some about 7'x12'.... also has anyone framed edges of doors with aluminum channel? thinking 2" channel would work perfect for that? Also another question for those who work fiberglass... I wonder how covering 1" foam with glass would work for under bed? if its strong enuf and if it would be lighter?? also thinking, after reading http://www.goldbrand.info/motorcykelhusvagn2.html that I may try a "1/4" ply -2" foam- 1/4" ply" sandwich and cover that with fiberglass and with aluminum rails of 2" square imbedded where springs will bolt on?? Think this would be strong enuf not to flex and be lighter then steel frame with ply bolted on top? My trailer, if I decide to go this route will be 11" long and inside width of 54 inches approx
