I have one method to prevent the long tape in the T from sticking to itself
It is frustrating when you have to remove and redo your T again and again... this method saves your T a lot of times!

Cut a short piece of tape (yes another one), just long enough to warp it flat around the long T 1,5 or 2 times.
You will get a flat square in the middle of your long tape.
I put that square so it will end past the narrow part of my legs and a little before the part that will stick to my back.

Even if you mess your tape between your legs, that self sticking mess will stop at the square. And the end of your T is safe and flat.
Your T is saved where it matters

Hope it helps.
