Step 6: Now the scary parts start
Right now you have a bow shaped object, and you have to start working it into a bow. Start by easing all the corners, this will help prevent "lifting a splinter" when you start flexing the bow. After that, cut a couple of thin wedges from scrap and lash then one inch from either end of the limbs.
Now make a heavy long string from some cord and we can start working the bow.
