These steps are for the traditional blanket and bedspread. If you use a comforter or thick quilt, you can simply place it on top of the sheets without tucking it in.
Pillows go on top.
Put the bottom sheet on the mattress. If it is a fitted sheet, it will have sewn-in corners and you can fit it snugly over the mattress. If it s a flat sheet, follow step 2 to make hospital corners. Tuck the sheet snugly under the mattress at the foot of the bed and the head of the bed. Tuck the corners under the mattress on the long sides, making sure that the folds are flat.
