This video explains how to properly fold fitted sheets. The first step is hold the sheet with the pattern, outer side closest to you and put your left hand into the first pocket and your right hand to the second pocket. Put your right hand over your left hand and flip the sheet on top of itself. Keep your hand on the top sheet and follow the edge all the way down to the third pocket. Place your hand on the underside (non-patterned part) and match it to the first two pockets, and then flip it over. Follow the edge down to the last pocket. Put your hand on the underside and again match the pockets and flip. Then take the elastic and shake to straighten them out. Even out all the edges, and then lay it on a flat table and fold it.
