Here's my method, perhaps someone can point me at another way that will fix the short himo problem.
Step into hak. Bring rear panel up around waist, slide rear himo under belt from above at my sides, bring the straps to the front and tie in a bow. Bring front panel up and in front of belt. From above, slide top few inches of front panel, including himo, between belt and gi, pulling front himo through. Wrap front himo around back, around belly, around back again, bring to front and tie in a knot. Put the free ends in a neat flat bow.
