CAST OFF //
You need to make sure that you have enough yarn remaining in order to cast off. For a blanket, this needs to be at least eight times the length of a giant knitting needle. If you don't have enough yarn left on your bump, join on another bump of yarn or undo the previous row before casting off.
Got enough yarn? Now it's time to cast off your beautiful creation!
Knit two stitches, then slide the first stitch over the second stitch and off the needle leaving only a single stitch on the needle. Knit another stitch then slide the first stitch over the second stitch and off the needle. Continue this for the remainder of the row, then pull the yarn end through the last loop and tighten.
