Then I began to unbraid the strands of the stems just up to the ligatures.
Now I had a much finer handful of strands to surround my handle core.  I tied this bundle up too, and carefully straightened the strands, minimizing the crossings.  One thing that is NOT visible here is how I snugged the core up tight to the top of the handle.  I took a couple strands and tied them around the bottom of the weight.  When I pulled the strands tight, it drew the weight up very tightly to the top. I put a square knot in these strands and then draped the remaining ones along the length, just as you see here.  The white threads are tight too.  The core is pretty secure.
I rolled this core against the table to make it rounder.  I actually put it on the floor and rolled it under my foot too, but no pictures of that.  Since the core isn't round (it's a kind of figure eight in cross section, remember?) but it is filled with moveable material.  This really smoooooths out the contour of the core/strands for a nice round handle.
