awning covers

I read a thread here several weeks ago about making your own awning cover out of PVC. I found a much lighter, much cheaper plastic drain pipe, cut about 25% out lengthwise. It snaps on and off easily, weighs about 1 pound, and has holes to allow the water to dry out, without the sun getting to my awning. Hope I load the pics right. This is my first try.
First time with photobucket. I copied the url but the image button isn't working. Any suggestions?
