hi kelly, if that silk is saturated right through with the glue, at the time of layup- the edges will finish up smooth- no loose ends
i like the funky pattern, looks very cool!
you could probably soak the rawhide in water, get the glue off it, and allow the hide to dry on a flat surface- you know it is bow size now- you might be able to use it on another- narrower bow.
holler if you need some more
cheers
