Officially called '"toggles," these little beauties are most often
seen as old-fashioned buttons on wool jackets.
I gave up on these stay rods because of the hours it was taking to find and prepare them myself. At the time I was using oak dowel rods and sanding them by hand was a real time stealer. Now that I have found a supply of them, they will be reintroduced in a select set of our slings hitting the market summer of 2016.
