Guitar strap for Jessica

My daughter's best friend since age 3 is a guitar player. She's a hippie at heart and we love her. She played in the talent show at school this spring using an old neon belt and some twine for a strap. She wouldn't let her mom buy her a new strap! But, I thought if I made her one, she couldn't refuse it. Not sure if she has let go of the belt and twine or not, but I know she has another option now! Used Man Sewing guitar strap tutorial
