These great bracelets are also made with t-shirt yarn, the small balls I sell in my http://www.lvly.nl webshop are also very suitable for jewelry making, you can find them here. The full tutorial on how to make these beautifull bracelets you can find on JTHQ which is short for Jewelry Tutorial HeadQuarters and they really know how to make jewelry.
To make it easy on you they even added a video!!!
