So super simple to do! All you need are some beads appropriate for your yarn, a crochet hook or bead needle ( or other gadget to get the beads onto the yarn ) and you are ready. Beads that are too big can fall off; if you find some beads that you really want to use, but they are too big for a single strand of yarn, you can use multiple strands, or after threading the yarn through the bead, bring the tail up and tie a knot above the bead. Loopy beads :0) I didn't show this in the video, because it only occurred to me now as I write this.
You can place the beads anywhere on the strands of fringe you like. Near the top, bottom, or somewhere in the middle.
You can put them on randomly, or place them in specific places. Use different colors, whatever you like.
Here is a short video. Have fun adding beads to your fringe!
