Mask Face - 2011 was released on: USA: 2014
To create a homemade face mask, you can follow these steps: Choose a fabric like cotton or a blend that is tightly woven. Cut two rectangular pieces of fabric, about 10x6 inches each. Place the fabric pieces together, with the patterned sides facing each other. Sew the edges, leaving a small opening to turn the mask inside out. Turn the mask right side out and press the edges. Add elastic bands or fabric ties to the sides for securing the mask to your face. Optional: Add a filter pocket for extra protection. Wash the mask before using it.
