I have seen them where there are actually two straps, or maybe one long one wrapped around the wrist, but so two ends come forward. One, from the thumb side, is wrapped over the string,just below the arrow, the second wrapped the same way, but over the first, and from the finger side of the string. This makes it way easier to hold the wraps with just finger and thumb pressure. The first tab is shorter than the second, which must be long enough to fold over and be grasped between finger and thumb. What I saw worked pretty sweet.
