In casting off the yarn is tighter and is a little harder to use. You should have one loop on each peg. Pull the loop off the second peg and put it on the peg to the left of it. Pull the bottom loop over the top loop. Take the loop on that peg and put it on the empty peg. Repeat with the next pegs until the loom is empty. The finished project will look like the second to last picture below, and if you turn it inside-out, it will have a striped pattern like the last picture. Congratulations you have knitted on a loom!!!
