Lark's Head Stitch, Fringe

I don't make a lot of fringe. I put some on a shawl in the late 70's, and it tangled so much that I don't wear that shawl often.
This is not really a crochet stitch. I think of it more as a latch hook stitch.
I do occasionally use it to put trims on smaller items.

 These zebra striped slippers for my nephews needed a mane.

These slippers for my sister are cuter as fuzzy "animals". I glued on eyes and made small ears before putting on the fringe, which covered them.
Very simply, I cut yarn to 3" lengths. If you want longer fringe, cut longer strips. The knot will take up some of the length. Fold the yarn in half. Put your hook behind the post of the selected stitch. Pull the fold of the yarn part-way through. Catch the ends and pull through the loop. Pull on the ends until they are tight. You may want to trim after all the fringe is on to get it even.
I'll also be using this to put a mane on the donkey for my Nativity sets.
