That's a great idea and I've been wanting to do it... but so far haven't quite figured out how to hold it down on the bottom when I want it all closed up and still be able to roll it up
I know a lot of greenhouses use the "wiggle wire" things... not sure if that's a viable option for me or not.
Well, it took 2 years for me to just figure out how to cover the framework (after the original, made-to-fit, cover disintegrated... another 2 or 3 years and I'll figure out the roll-up sides (maybe)
