In addition to the knit stitch, you will be purling, knitting two stitches together, purling two stitches together, and finally knitting into the front and the back of a stitch.
Knit two together (K2tog) and Purl two together (P2tog) are decreases, and by knitting into the front and back of a stitch (KFB) you will be increasing.
This scarf starts out on forty stitches, and this is decreased down to twenty after ten rows. At the end of the scarf, we will increase back up to forty stitches, work for ten rows and then bind off.
You will need two balls of Cascade Cash Vero and US Size 9 needles to make this scarf.
The written pattern is available for download on Craftsy, just click the picture below. The video is below, and goes from cast on to bind off. I tried to show as much as possible in the video. There are also links within the video for the stitches used in the scarf.
