I have one that I fringed by pulling out a bunch of threads at the edge and then taking a group of the threads (like about 5) and tying them in an overhand knot up against the edge of the fabric. I think I used a crochet hook to help pull the thread through.

You can also do it by machine stitching a line where you want to start the fringe - either straight or zigzag, then pull the threads out up to the machine stitching. The first method looks like little tassels when it's done and the other looks like regular fringe.
