I have used similar duck tape straps for different things but one problem i have encountered is that eventually the tape looses its stickiness so instead i ended up doubling a rubber band so that the strap could stretch instead of fastening and unfastening the tape. here are some pictures of what I mean. In this case i used it as a strap on a knife sheath so i can strap it to my calf.
