Zipper pull tab

I tried most popular printed zipper pull tabs but found that they don't last very long. They either break because the link between the pull tab and slider body is made of plastic, thus too fragile or the pull tab pinches the cord and loosens over time. So I went to the drawing board and reduced the amount of parts while using the tensile strength of the braided cord. I came up with this simple yet strong zipper pull tab.Note: Best used with 2mm braided cord. Instructions Cut a 2mm cord, aproximatly 12cm long and gently melt the ends with a lighter (optional). Tie one end with a simple knot, slide the knot to the far end of the cord. Insert the cord thought one of the bigger holes and pull the knot inside the hole. Thread the cord through the slider body and then through the other small hole on
