im trying to understand what you did there...
watched 3 times...
so you taped over the bit you just hung. then laid the next piece over the tape.
then cut on the side of the piece you hung over the tape...
then at 2.40, you take off the 2 little bits you cut. ok i got it. using a4 paper to simulate what you were doing.
upshot is your a cheater! great cheat though!
