Hold two craft sticks together and start out your craft with your first color. Holding the sticks can be tricky so for kids I recommend gluing the sticks together. You can just use regular craft glue for this.
Wrap the yarn around one side diagonally approximately 5-6 times. Looping over the initial start so it will stay tight.
Loop under the craft stick so that you can go in the opposite direction.
Going the opposite direction, wrap the yarn around the other side 5-6 times. You should have an X at this point.
Next, wrap the yarn under the craft stick again.
Bring across the top diagonally. You should be going in the direction you started off the craft with.
Wrap under the craft stick and across diagonally (the opposite direction) again.
Continue to wrap the yarn over each side and across diagonally until you reach your desired number of rows.
To change colors tie the two pieces of yarn together. Cut off any excess so you can easily hide the knot.
Continue wrapping the same as before. To change colors again just use the same tie-off method.
Once you have reached your desired color combo and length tie it off leaving extra yarn to create a hanger.
Tie off the back in a knot so that you can hang your craft. I also recommend adding a dot of hot glue to secure the yarn and hanger.
