Type of seam on DIY hammock footbox, shelf, zipper, etc
Planning to make a DIY hammock. Was wondering what type of seam would you use to join the body to the footbox, shelf, zipper, etc. I did a search and didn't come up with any thread that directly addresses this. A lot on seam sealing and flat felled seams, but I want to put grosgrain on the seam for a finished look and I am not sure how that would work on a flat felled seam. I picture the grosgrain on my seams enclosing the seam.
I drew a picture...yes it is bad, and yes my seams look even worse! They've held up so far! (have made 2 tarps and 3 hammocks- without an integrated bug net, foot box and shelf)
In the attached picture, 1. what seam would you use and where? 2. In picture "B" would you sew seam "c" or just skip it and use sew on the two larger lines?
