I haven't stored my sheets in my linen closet for years! Every bed has 2 sets of sheets. I fold the sheets as most everyone else seems to do, and fold the pillowcase around it (or you can slip the sheets into the pillowcase). Then I put the extra set between the mattresses of the bed it is for. I either slip them in at the foot of the bed, or the side - whichever is more convenient.
When we had babies in cribs, I folded the crib sheets, put them in a plastic bag, and slipped it between the mattress and springs. This way the sheets are handy and easy to get to when I want to change them, and it frees a tremendous amount of space in my linen closet for other things. This was really helpful when there were 6 of us in the house!
