There are a few different ways to make fringe and lots of ways to change the look of your fringe even if you make it with the same method.
First, you need to decide how long you want your fringe to be, how thick (how many strands and what colors), and what style.
What most people probably think of when they think of fringe is the simple fringe, made much like the knot you make when working latch hook rugs. On this page, I will cover basic fringe made with the larkspur knot.
First, gather your tools -- yarn and the object you are going to use to wrap the yarn around. One option for this is a special fringing tool, like the one shown at right. This particular one is the Susan Bates Trim Tool. According to the paperwork that came with it, it can make fringe from 1 1/2" to 15", tassels, and rug yarn. I am focusing here only on general fringe. I will not go through everything this particular tool can do. There are explicit instructions on how to make the various lengths and types.
If you don’t have a special tool, you can wrap the yarn around anything you have in your house -- a piece of cardboard, remote control, PDA cover, DVD. All that matters is that it’s the right size. You want an object close to the length or width you want your finished fringe to be. Since you are wrapping the yarn around an object, you will be getting strands twice the length, plus a small amount for the thickness of the object. However, since you double the strand to make the fringe, this evens out.
Once you have a good amount of yarn wrapped around your tool of choice, cut the wrapped yarn straight across, so that you get several strands of similar length. Don’t worry if it’s not perfect -- when you're finished, you can trim your fringe to get the length more exact.
After the strands are cut, you will use the larkspur knot to attach them to your piece. You can follow along with the pictures or video below.
