Since the concert uke is a longer instrument, I can't hold it against my chest with my right arm. So I need a strap. Instead of buying one I decided to make my own using the instructions I found here. I bought three sets of 45-inch laces: black, gray, and red. But I did a couple things different from the instructions.
Instead of tying the ends of each set of laces together, I cut off the ends and sewed them together. This made for a cleaner look once I braided the laces.
Instead of tying the ends of the shoelaces together at the end, I cut the ends off, lined them up and sewed them together. This, too, also made for a cleaner look.
At first I tied the strap just above the nut. In that position the strap interfered with my left hand just a bit. So I moved it to between the two sets of tuning keys.
It works great and it looks pretty good.
