A Great Guitar Strap will be made with good Leather..
There is a Much better grade of leather to buy than
thoes Bellies. If you want to use the bellies Line them
with 1-2 oz natural pig skin.
If you use a better leather to make the straps do as
othere have said and use the Gum Tag.
Dont mean to be a Critic, I know what has worked for me.
