i remember when I took my first knitting class... ribbing was the hardest thing to get used to! always remember that with k1p1, you knit the stitch with the yarn in the back, then bring the yarn between the needles to the front of your work. then, purl a stitch. after that, bring the yarn between the needles to the back of the knitting. does that help?

good luck and dont give up!
