I use commercial fisherman's seine twine along with a handmade brass button (from my brass scraps) for cinch up closure to ensure a perfect fit for various wrist sizes. Please note that the commercial fishing line is new line...unused for fishing, only used for my bracelets/cuffs. To see an example of the cinch up closure please follow this link.
My bracelet measures 1 1/4 inches wide.
*All of my work is 100% handmade by myself and I use recycled/upcycled materials and found objects as much as possible
