There's two ways. First you can stretch to the max then wrap it tightly while pressing on it with your thumb and it will adhere or you can stretch it and pull it through the wires at the end of your wrap, this jams it in between the wires and it can't escape. I found that it's almost impossible to unwarp the tape once it's been properly applied, that's why i found that a razor blade was the easiest way to get it back off. If you've used it before you know that it doesn't come off easily even though it has no adhesive. The longer it sits on the wires the more it seems to bond. I'm not sure how it works but I love the "Non-sticky" aspect of the tape. treblig
