2torial #0630: Learn2 Make a Bed (Continued) Put on the bottom sheet   Sometimes you have a fitted sheet, and sometimes you don't. If you have a fitted sheet, with elastic on the ends and pre-formed corners...   Stretch the sheet over two corners at one end of the mattress.   Walk around the bed and stretch the sheet over the other two corners of the mattress. If you have two flat sheets, take one of them now and...   Hold the long end of the sheet (the side without a hemmed edge) with both hands, and stand next to the bed.   Flip the sheet out over the bed, so that it billows out and spreads over the mattress. Position the sheet so that it hangs evenly over all sides of the mattress. Make sure the long edges are parallel to the floor and hang below the bottom of the mattress.   Take the short end of the sheet, and tuck it snugly under the end of the mattress. Make sure that the sheet lies smoothly between the boxspring and mattress.   Go around to the opposite (short) end of the bed and pull the sheet taut. Tuck the sheet under the mattress as above, maintaining the tension you've created.   Move back around to the long side of the bed. Tuck the edge of the sheet under the mattress. This should create a vertical fold but won't if the short edge of the sheet is bunched under the end of the mattress.   Go to the other side of the bed and repeat the last step. This is where you can tug firmly on the sheet to create a taut surface. Step 2
