Take the cat wisker new before its (seperated) rool it up and tie it with floss (i dobble the floss and twist it) leave floss ends long so you can tie to bow string, now unstring the bow slpit the string in half, insert one end of floss and cat wisker in to the bow string, restring bow. Now tie to bow string on first side now tie a dobble not on other side, leave about 1/4" tags after cutting floss and use a lighter to melt the ends of the floss down. They will last longer than your bow string.
