The 6-mask panel fits on a Fat Quarter of any fabric (including Petal Cotton or Organic Cotton sateen, my favorite for face masks because of its tight weave). A yards yields 20 to 30 masks depending on the fabric width. For kids and those who prefer a more joyful Halloween style, 2 other Halloween-themed panels are available in my Mask Collection, with pumpkins, witches, cats, etc in purple and orange colors or black and white.
