Finished up wrapping my Tinker longsword handle with waxed linen thread. The process was extremely simple:
Start at the small end of the handle, I started on one of the thin sides of the handle but it's your preference, by placing a dab of superglue / epoxy (I used Gorilla SuperGlue). Let dry.
Keeping tension on the thread, begin wrapping. I recommend wearing gloves for this otherwise your fingers wind up waxy and raw (Thanks for the warning Mike!)
OPTIONAL - if you want, every now and again you can use a drop of glue on the thread. I did this once then realized it wasn't necessary IMO.
To finish, more glue 8-D
If I putz around with this handle again it will be to put a leather wrap on over this layer of cord. This will help fatten the handle a bit (and wind up with a wood -> cord -> leather -> cord -> leather construction). Eventually I might even make my own wooden core for a new handle, but we'll see.
I didn't think to take progress pics, so here are two finished shots (crappy quality = cell phone)
