Make a Reusable Coffee Cup
1. Start by gathering supplies such as fabric, elastic bands, and scissors.
2. Cut out two rectangles of fabric that are slightly bigger than the diameter of your mug.
3. Measure the circumference of your mug and cut two strips of elastic that are 1/4 inch wider than the diameter of your mug.
4. Place one strip of elastic around the top of the mug, with the ends overlapping each other.
5. Place the second strip of elastic on the bottom of the mug, making sure it's centered.
6. Secure the elastic in place by tying a knot at the back of the mug.
7. Fold the excess fabric over the top of the mug to create a pocket for your coffee.
8. Fill your mug with your favorite beverage and enjoy!
