Semo, I did one like don showed off. Very nice Don!
I used some very thick white cotton cord or string. I bought a spool of it at a garage sale. When pulled tight it's about 1/8" diameter. Anyway, I wet it good and wrapped the handle. After dry I gave it several soaking coats of Water based polyurethane.
But, it stayed white, so the TB3 method might be a better approach or you can die the material before application. I do the same thing on the little kid bows I make only use conventional weight cotton string. They seem to be holding up. All in all, I like the look of Don's a bit better than mine.
