Cut your yarn twice as long as you want the fringe to be, I cut my pieces 8 1/2" or 22 cm.
Dig out an appropriate sized crochet hook that will hold the number of strands you are using for the fringe. My pattern called for 5 strands of the worsted weight yarn and I used a 4.5mm hook.
With the right side of your knitting facing you, insert the crochet hook from the back to the front
Gather the number of strands you will be using and hold in half over the hook
Pull the strands through, adjust the ends if needed to be even
Pull the yarn tails through the loop
and snug up the yarns
You can decide how close together you want your fringe. I left 3 sts between mine. At anytime you can undo a fringe if you need to make adjustments. It's really pretty simple, I hope you give it a try!
