Get a brave willing grandchild and make a deal with them to be your 'model'.
Take your instant plaster cloth that you got from a craft store, and cut into about ten inch lengths depending on the size of the face you wish to use it for.
Rub vaseline or face cream on the child's face getting the hairline and eyelashes fully covered.
Place the warm wetted plaster strips around the face a couple of times. Fill in over the face first covering the forehead and chin, last covering the upper nose and eyes - WITH THE EYES REMAINING SHUT!
Cut short strips to cover the nose and almost cover the nasal area, but be sure to leave hole enough to breathe well. You might have to make an additional 'deal' at this point.
May blow gently with a just-warm hair dryer for a minute or two, let cool, then remove mask. Start pulling off hardened mask at the chin and hairline first.
Set aside to dry briefly, then enjoy! And add in an extra 'prize' for good measure!
