Stockinette Stitch
Knit one row, purl the next. It's smooth on the front, bumpy on the back, and its edges tend to curl.

Swatch first. These numbers are only right at your gauge, and the starting values above are typical figures rather than yours. Work a 4" swatch, measure it, and enter what you get.
