There are a lot of basic or vanilla sock patterns out there. This is the one I use for myself. This pattern makes a top-down sock with a slipped stitch heel flap and a flat toe, worked on double pointed needles. You can knit the leg and top of the foot either in stockinette stitch or ribbing.
This pattern is given in several stitch counts: 56, 60, 64, 68, and 72 stitches for either fingering or sport weight yarn. Socks are pretty personal, so you’ll need to find the happy medium between your yarn, needles, gauge, and leg/foot size for the best fitting socks.
You’ll need 300-400 yards of sport or fingering weight yarn, double-pointed needles in a US 1 or 2 (or the right size for your gauge) and a tapestry needle to graft (kitchener stitch) the toe closed.
