Sorry for the bombardment of videos, hope no one minds (I like videos :p)
Today we have a tutorial from Epicurean Cyclist that shows you how to wrap just about anything with twine. Very slick method. My only recommendation is to run your “loop” of twine underneath the bars so that when you finish and cut the ends, the little nubs of the cut twine are on the underside of the bar and don’t show. It should also be mentioned that twine, like cloth tape, takes well to shellac and provides weather resistance, makes the twine stay in place and adds some color to it.
