It can help to use a larger needle to bind off with to make sure you don’t do it too tightly. Otherwise, the the end of your knitting could pucker up. [6] X Expert Source Jen WebberKnitting Specialist Expert Interview. 4 August 2020.
Make sure to leave the strand about 8 inches (20 cm) or longer to ensure that you will be able to weave it into the edges.
Keep weaving the yarn in and out of the stitches along the edge of your scarf until the strand is too short to weave any further.
For example, if your scarf is made from a medium worsted weight wool yarn, then choose the same type of yarn for your fringe.
For example, if you want your fringe to be 4 inches (10 cm) long, then the cardboard will need to be 4. 5 inches (11 cm) wide. Make sure the cardboard piece is long enough to wrap a significant amount of yarn around it as well. The piece should be at least 10 inches (25 cm) long.
Make sure to wrap the yarn around the cardboard width-wise, which is the part of the cardboard that you have measured for your fringe.
Keep in mind that the yarn strands will be twice as long as you want them to be, but this is because you will be doubling them up along the edge of your scarf.
Do not pull the yarn all the way through the stitch. Use a crochet hook that is small enough to easily fit through the stitches on the end of your scarf.
Keep repeating this process until you have added a fringe bundle to every stitch on the end of your scarf.
