Cut fabric about an inch larger than mask all the way around. Snip the knot off one end of the elastic and pull the elastic out of the mask by the other hole. Set the elastic aside for later.
Press fabric to mask, making sure to press down and smooth wrinkles where mask bends. Wrap and secure edges around the mask, trimming any excess fabric as you go.
Note: If you do the cat’s eye mask, you need to take a snip at the point between the eyes so you can fold the fabric the appropriate direction.
Next, snip a hole in the center of each eye, and cut radially to the edge of the eye opening.
Push cut fabric from eye hole through and secure to the back of the mask with more glue or Mod Podge. Poke holes through the mini-grommets for the elastic band. I used my seam-ripper for this task, because the point seemed the right size. You could use a darning needle, too.
Apply two more coats of Mod Podge, waiting for each coat to dry in between. Don’t forget to re-poke the holes for the elastic each time.
Decorate the mask to your heart’s delight. I let the kids each do one – they chose feathers, bows, and jewels. We used glue to secure the decorations.
