I've recently bought a Lakota Leathers round braided strap and it is awesome!! Super soft and super comfy. I keep it on my mando in my Calton case and I've noticed that the strap will slip off the tailpin if I'm not careful when I put the mandolin on me. I have seen some folks weave a thing piece of string in the strap hole to secure the strap on the tailpin. Any suggestions on this or how to make sure that the strap doesn't slip off when I throw it on?
