Crocheting a rib stitch won't get you ribbing exactly like a knit rib, but it is possible to come close. Or, if you're looking for a way to add some texture to say a basic scarf or cowl or even a little baby blanket, then I'd recommend making a double crochet rib that looks like my example here. Plus the edges have a sort of chevron look to them and actually look much nicer that the edges would of a piece that was just made with rows of double crochet.
The oh so simple secret to this? Double crochet in the back loop only of every row, and after turning at the end of each row, chain 3, but do not count this as a stitch. It's that simple!
