Vertical wave bracelet

This bracelet is one I made for a friends birthday. Her birthday isn't until October, but I wanted to get a head start ;) It is twelve strings wide and the knotted part is 5 inches (14 centimetres). For me that is a total of 84 rows. I did not create the design for this bracelet. I found it here chibi_ragnarok's tutorial on friendship-bracelets.net
