God Bless Sam Harper for helping so many people get into making wood bows, but damn him for the fiberglass tape suggestion...
Not sure how to help you there Eric. You could probably heat the tape with a heatgun to release the glue but that much heat probably wouldn't be good for the back of the bow. On your next attempt you could try an unbacked bow...those are alway nice
Or you could use paper, linen, silk, rawhide, burlap, anything but FG tape
Burlap is easy, cheap, most feed stores will sell you a burlap sack for a few pennies. Good luck either way and welcome to PA.
Mike and I must have typing at the same time
