Since your house is clean, you'll want to entertain. First, pay attention to your table. Don't buy table linens that can't take hot water and machine washing. Linen responds better to stain treatments than cotton, but linen can be damaged by bleach.
Most tablecloths have to be ironed.
Begin at the center and work out. Iron flat, not folded. Iron on both sides, starting with the back. To save ironing, get cardboard tubes and roll your tablecloths around them for storage. Or fold them in thirds and hang them from a padded coat hanger.
