The awning in the avatar pic does store in a bag, but it's not a bag awning in the sense that it doesn't live on the awning rail full time. It's a pole and rope awning from JC Whitney - a cheapie until we could decide what we were going to do there permanently. I have some cool outdoor fabric and will eventually make a nicer awning using this one as a pattern.
We have one of the pole and rope awnings from VTS for our Caravel
- love it! Hope my home-made one turns out half as nice!
