Considering trying a "harlequin" wrap on my drops. How much tape?
 

For those of you that have pulled this off, how much tape does this style of wrapping burn through, versus a traditional wrap? None of the LBS around here carry cotton tape, so I'm going to have to order it online. I want to make sure that I've got enough to realistically finish the project.

never tried it, however, considering that a normal wrap, has the tape overlap itself by half its own width, and for a harlequin does not; I'd say that you need to halve the length of the tape -on top of there being a second color. ie- same total amount of tape will get used, but it is now split into 2 different colored ribbons of half length. (per side)

4 rolls I used 2 of each color. In my case yellow and black. I did have a bit left over.

Thanks! Now, I've just got to work up the whatever to actually do it. (I'm a novice when it comes to wrapping drops the traditional way.)

Yep, you have the theory right. But in practice you still get small amounts of overlap, so it'll take a bit more than half the length of an ordinary wrap.
2 rolls per side and you'll have quite a bit left over.

Took me a couple of tries to get mine done, one side I had to wrap and unwrap a couple of times. FWIW that was on butterfly bars, I have wrapped plenty of drop bars in the past. Take your time and don't be afraid to stop and rework if necessary. Definitely will give you something out of the ordinary to set your bike apart.
