Hey all, I have the notion to build myself my own pop-top camper and what fabric to use for the walls of the pop-up portion is a bit of a conundrum to me. I've taken a look at FWC walls and have a CVT RTT, I'm wondering if there's a middle ground between these two. I imagine whatever FWC's are using it's hard to get and likely hard to work with. My mother, who is gifted on the sewing machine and who has a semi industrial sewing machine will be making the fabric walls, I need a fabric that is at the very least water repellent but thick enough to stop a decent amount of wind. I'm kind of a fish out of water in this department, can anyone learn me up? Thanks.
