Probably too "nerdy" for most, but I recycle my old useless tubes and use them for wrap.
There is a reason for this....I sweat profusely and seem to destroy tape quickly. I use the old foam rubber tube type cushion used on the older road bikes and then cover that with the used tube. I cut the tube around the inner diameter, cut out the stem area, and wrap just like regular tape, securing the ends with tennis racket tape.
