Who is this project for? Women What advice would you give someone starting this project? The perfect length of the string depends on the size of the beads. As I used some bigger beads (12mm) in my design, I needed extra length to fit my wrist. That's because the beads themselves take up space on the inside circumference (bigger beads take up more space than smaller beads). I use a bottle neck to measure the perfect inside circumference of my bracelets. I marked the neck of the bottle with a permanent marker with the different sizes of bracelets I usually make. For measuring the bottle neck I used a tape measure. I use an additional shortener clasp to keep the wraps together when I wear it as a braclet.
