I am getting further along on each one. I make it a practice to back all of my attempts being new at bowmaking I want all of the insurance that I can get. The first bow I used fiberglass dry wall tape but on the last two I used burlap which I believe to be much better. After each scraping I flex the bow 30-50 times making sure not to flex the wood to much. I may be leaving it in a pulled condition to long though....chuck
