|Pillow By Day...|
|...Blanket By Night|
On one side of the blanket has a pocket that is approximately 1/3 the width of the blanket.
Flip the blanket so the pocket is face down and fold in half upward.
Fold in half again, so that the blanket is folded to the same size as the pocket.
Turn the pocket inside out so that the blanket is inside the pocket, and now you have a pillow!
