This stitch works so well for hair texture. You can change the texture and size by changing the amount of threads that you use or use a yarn or different weight.
Any description that I give you will sound like gibberish, I might as well write the Jabberwocky poem out for you, so the best thing I can do is show you how I do it! The video below shows you the stitch and then it will show you the stitch in slow motion with me describing how to do it!
I really hope this helps, it's one of my absolute favourite stitches :)
