Thanks for the response but I still don't understand. I may have not been clear in my question before. I'm kind of new at this.
The M1 is going to cause two stitches to be the same, sitting next to each other and thus disrupt the ribbing pattern. If the stitch before the M1 is a purl, don't I have to M1 with a knit stitch. But than the next stitch is another knit and then purl thus putting 2 knit stitches together.
