The hdc rib stitch, when done horizontally back and forth, makes it look like vertical knit stitches have been worked. I use this stitch in several of my tutorials--thus making this video necessary for those who need a closer look at how this crochet stitch is done! I hope it helps, and let me know if you have any other questions.
To make this stitch, I use worsted weight yarn and a 4.25mm crochet hook.
