I was implying that at all, sorry if I came off that way. I was interested in your information and trust the conversation is of interest to the DIY folks on the forum.
I believe I tried the hot cut, folded hem approach after wrestling with trying rolled hems on curves after I read some info on sewing techniques that I found on Stephenson's Warmlite site. I have had one their tents for a few years and have always admired the design, construction of it, and how well it does what it is suppose to do.
But back to the curved surfaces and rolled hems for a minute. The basic problem is the geometry, it just doesn't want to fit when you do a rolled hem. The bigger the hem and the deeper the curve, the more it doesn't want to fit. You can force it to happen but it likely will not look as neat as the rolled hems you see on straight edges.
