I'm very new to knitting. Thanks to this site I figured out how to do a 3x3 rib stitch. I've reached a point in my pattern where it says,
"Place markers at both ends of last row. Starting with a K row, work in st st as follows:- inc 1 st at each end of 5th and eery foll 6th row until there are 93 sts. Cont straight until Back measures 13 cm, 5 in from markers, ending with a ws row."
What do I use for a marker? How to I knit around them? Am I supposed to knit around them or inside them? If I'm knitting inside them, what's the point?
Thanks for any help you can give me. I've attached a picture of my ribbing so far
