How to K2tog or Knit 2 Together

Simply put, knit 2 stitches together. Done to form round edges, gradually decrease the number of stitches like in arms or for socks. You will have one less stitch for every two you knit together. So if you K2tog on your 20 stitch swatch, you'll have 10 stitches left.
