I will need about 12" of hair for a basic bracelet or 18"+ for a wrap bracelet, cut from the center of the tail, about a pencils width in thickness. For cuff bracelets, I will need about 12" of hair, a markers width in thickness. Standard women's bracelet size will be 7" or I can custom size them specifically for you. I will need your actual wrist measurement for custom sizing. Length will be added to accommodate for a comfortable fit. If you do not have a soft measuring tape, you can just cut a strip of paper to fit your wrist and send that along with your hair. Basic and wrap bracelets include a sterling silver horseshoe charm and Swarovski Crystals. You also have the option to add an engraved sterling tag or additional/different charms.
