Cut 40 to 50 pieces of yarn that are 11 inches long.
The easiest way to do this is to wrap the yarn 20 - 25 times around an 11 inch cutting board or a piece of cardboard.(You could also wrap the yarn lengthwise around a ruler to get 12 inch pieces.)
Cut the loops on each side to end up with 40 to 50 pieces of yarn the right length.
Step 3: Cut the toilet paper roll
Measure 3/4 inch in from the end of the toilet paper roll and mark all the way around it with a pen.
Use a craft or utility knife to cut through the paper roll along the pen marks.
Step 4: Attach yarn with a lark's head knot
Fold one strand of yarn in half.
Put the loop through the paper roll.
Bring the ends of the yarn over top of the paper roll and thread them through the loop.
Pull the yarn ends tight and adjust it so the yarn around the roll is snug.
Step 5: Add the rest of the yarn
Continue adding yarn to the roll, pushing it so the yarn strands are close together.
Add more yarn until the entire roll has been covered. Make sure there aren't any bare spots where the paper roll will show through.
Step 6: Shape the yarn hat
Crumple up a small piece of tissue paper to make a 1-1/2 inch ball.
Place the tissue paper inside the paper roll, pushing it up a bit. This will create the hat shape that you'll tie in the next step.
Take another piece of yarn and tie it around the yarn strands above the tissue paper ball, about 1-1/2 inches above the paper roll.
Now remove the tissue paper and push the yarn inside out through the paper roll, creating the knit hat look.
Trim the ends of yarn that stick out from the bottom of the hat.
Step 7: Attach pompom and ornament hanger
Add a small dot of hot glue to the top center of the hat.
Place a pom pom in the hot glue.
Take another piece of yarn (cut a piece to around 8 - 9 inches if you don't have a strand left) and double knot the center of it around the base of the pompom.
Tie the ends of the yarn strand together to create an ornament hanger.
Your yarn hat ornament is complete!
TIPS:
1. Try to use the strongest paper roll you can find, whether it be a toilet paper roll, a paper towel roll, or a wrapping paper roll! The thicker cardboard is easier to cut and keeps its shape better with the yarn.If your paper roll is flimsy, it may be easier to bend it and cut it with scissors, instead of cutting around it with a utility or craft knife.
2. If you don't have tissue paper you can also use a cotton ball or kleenex to shape the ornament.
