Fold the blanket up from the bottom, once again into thirds. Flip pocket over the blanket. Smooth the edges and fluff for a perfect pillow. Convert back to a blanket by simply flipping and unfolding the blanket."
The pocket is at the "top" of the blanket. You are folding the blanket into thirds, lengthwise. The blanket should be longer than it is wide, and be the width of the pillow pocket. If you were to flip the blanket over now, the pillow pocket would be fully visible, with the open edge at the top. The blanket should now be folded to the dimensions of the pillow pocket. To do this, reach one hand into the pillow pocket and grab hold to the edge that is sewn to the blanket. Hold the open edge of the pillow pocket with your other hand. Pull the inside edge of the pillow pocket toward you while simultaneously pulling or flipping the free edge away from you and around the folded blanket.  It may help to think of it this way: the pillow pocket is being flipped inside out and you are stuffing the blanket into the flipped pocket. It may take a few tries to get the hang of the flip.  It should pop out of the pillow easily.
