I agree with Fly Goddess. Wrapping up the ramp allows me to keep the wraps nice and close. If one wraps down the ramp
loose and not perfect wraps would need to be handled. I like to keep it simple.
I'd suggest obtaining a carbon fiber arrow from an archery shop. Practice, practice. Not only practice the wrapping but also whatever coating you might want to play with. After practicing one can use a razor blade and cut off all your mess until the next time you practice. Did I mention? Practice??
Works for me.
