First sale through my Etsy shop!!! This ukulele strap is made to order. To supply the measurement of your strap length to fit your preferred posture please use a piece of string around your neck and dangle it close to the upper edge of your ukulele sound hole keeping your ukulele close to your body at the height you normally play it when standing up. Then lay the string on the table and using a measuring tape and supply measurement in millimetres. I will then subtract the snap hook measurement from that and you will have the perfect fit. Materials: Polka dots Grosgrain ribbon with matching plastic colour hook. Check out my video guide that shows you how it works and how to measure your strap prior to ordering. I hope it is useful!
