Materials:

1 old T-shirt (the bigger the better)

1 pair of scissors

1 ruler

Steps:

1. Start with a large T-shirt. Any old shirt will do. Seamless is a plus. 

2. Cut off the bottom hem of the shirt. Then cut 1 in - 2 in wide strips horizontally across the shirt from bottom to armpit. You can cut as many strips as you would like (I liked my thick strips the most). The more strips, the more strands your scarf will have. You can use a ruler to guide a straight line across the shirt, but don't worry if they aren't perfect.

3. Set the bottom hem aside. Stretch all of the remaining strips until they become ling, and the raw edges start to roll inwards.

4. Cut one end of the bottom hemline so it becomes a string.

5. Using the strip of bottom hemline, knot it around the strands to secure them in place.

6. Wrap the strip a few inches around the center of the scarf, and back over to meet the other ends. Knot the ends together tightly.

7. Trim the loose ends and tuck the knot underneath the wrapped fabric.
