Sounds to me hun, like they are asking you to do "garter stitch"
You know that bumpy ol' stitch that you first learned to do?
Except when knitting in the round you don't turn the work, doing one side n then the other (right side, wrong side). You have to work them both from the outside so you have to knit one row n then purl one row to get garter stitch in the round.
Hope that helps ya hun.
