I love Gaff - and all the pretty colors! It's my dancer's choice for taping marley seams, as dance floor tape is too slick for them. I have a steady supply of 2" Olive Drab, Black, White and Gray (not counting my rainbow of spike). And when it's not on the dance floor, I'm using it to repair set pieces/cracked paint in a jiff, covering flower stems (because every ballet has a bouquet in it somewhere...) and more!
GAFF for the win!!
