I could be wrong, but it seems with the half pyramid, I'm going to have to be making seams, given a max of 58" fabric width I'm dealing with. I can make seams, but I don't trust my current experience with seam sealing, with is limited to putting silnet on a commercial tent which was not silicone impregnated.
I just cut out a little scale tent, and scale "me", a mini-me. However, I've only got 8" vertical height on mini-me, and my feet are 11" long, so I might have to adjust.
What is a reasonable vertical height for a comfort zone in a tent? 12"? I'm talking about when you're lying down.
