The Sweet Dreams Mask pattern was revived during Sewing Club. I love the addition of buttons and cotton fabric. Not sure how comfortable it will be, but it sure is fun!
The pattern is just an oval with notches on either side for the nose.
After cutting out the fabric, get a friend to help measure elastic around your head. You don't want it to be too tight.
Sew on the elastic (careful so it doesn't get all turned around) on either side. Try on and say "Goodnight!"
