Thank you tump-lion.
I made the large triangles that go to the ground so that they don't flare out like a real whelen they just go straight down. and the smaller triangles (when deployed) use a small piece of bungee and usually get their own stake. On the one in the photo below I just cut the shape of the doors into the tarp rather than sew them on like I did on the first one, so there is no seam on the corners. The hammock suspension will go in the gap between the small doors and the large doors.
