Put a Pillowcase on a Pillow

This method is quick and easily performed by one person, no stuffing required.

Steps

Pick the pillowcase up by the closed end, opposite of the open side. Grab that seam with your palm, at the middle.
Without letting go, peel the case back over your arm so it is now inside out.
Grab the end or your pillow in the same fist that holds the pillowcase seam. The seam of the case you are holding and the seam of the pillow end will now be in the same hand.
Peel the pillowcase down over the pillow. Keep pulling, line up the side seams, and you're done.
