TBB talks of nylon being similar to sinew in performance. I THINK the recommendation was to prestretch it.
I'm wondering what form of nylon they used in their experiments? One could use the twine as a cable back. Or a strip of fabric glued down? I was considering trying to unravel and comb out some twine, then apply as sinew in wood glue. Or just lay the strings out.?.
They did a linen backed pine bow like that in tbb.
