A friendship bracelet is a bracelet given by one person to another as a symbol of friendship. Friendship bracelets are often handmade, usually of embroidery floss or thread and are a type of macrame. There are various styles and patterns, but most are based on the same simple half-hitch knot. The amount of thread used in bracelets varies depending on the pattern. The smallest pattern, a double chain knot, requires two strings while the candy stripe can have as 3 or more strings depending on the desired thickness.
