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 or any yarn you like with the appropriate needle size for the yarn.
Happy Knitting!
