Need a method to wrap H-bars with handlebar tape I've gotten good at wrapping drop bars, using conventional cork tape: You start at the end and work your way up, keeping the tension even and watching the overlap, and it works perfectly for me. 

But the H-bars on my Bike Friday have aways been a challenge. They're smaller and more finicky to wrap, but that's just a matter of time and practice. Specifically, getting the intersections at the bar joins to wrap cleanly has always been a problem: 



Over time, the tape will invariably loosen because of this. 

Can anyone suggest a method for doing this that will stay for longer? Should I wrap the main bars separately from the vertical bars? Is there some special secret way to do this? Or is this just a downside to this kind of bar? 

Edit: I wrapped the bars from the top of the barend down to the bottom, then getting the main handlebars. The below picture shows the problem area; note the separate piece of tape.
I'd wrap in two passes: first, from the bottom stubs to the join, just crossing over onto the ends of the main bar. Then tape this up tight, to squash it down. Secondly, I'd wrap from the tops of the bar ends around the joins and all the way up to the stem. The second pass should cover up the tape holding the first bit of wrap.

Maybe something like this (excuse terrible paint skills)?
