1. First, cut a piece of yarn that will end up being the length of the tie on string once the tassel is finished, set this aside for step 2. We chose the length of 18" because these tassels were going to be tied to the back of chairs.
In order to have the strands of the tassel come out to be the same length, wrap the yarn around a hard surface. We chose an 8"x10" box, but any size can be chosen based on how long you want the tassels to be. We wrapped ours around 20 times or so. This makes our final result have 40 strands. Adjust based on the thickness of yarn being used.
