Blinx -- I'll tell you my secret for folding fitted sheets...wish I could do Youtube.
Look at the right side of a fitted sheet. See the seam in the corner? Pinch the end farthest from the elastic and hold it up. Do the same thing with the other side and have your folding-companion (you *did* bring a folding-companion?) do the same thing. Notice that the elastic side falls in toward the middle of the sheet. Now fold bringing those 'pinches' together rather than the sides. You might have to shake the sheet a little or smooth in anything that is hanging out to get all the floppy part of the sheet on the inside of your folds.
It doesn't come out quite as neat as a flat sheet but not all messed up either.
