Where would I find these?
I have a 10x10 dog kennel and am looking for something similar to what they use on golf carts. That plastic roll tarp that you can hang along the top edge and roll down to the ground when it's bad weather to keep rain from coming in. Or something else
You have a few options. If you want to hire out the job, go to an awning store - check out a RV supply store or ask them if they know who does awnings and boat covers in the area. As the first answerer said, it is so simple and should not be too expensive.
