A tablecloth for an ordinary meal
Choose a cloth you can use comfortably, rather than saving every textile for a special occasion.
Check the size in place
Lay the cloth over the actual table and pull up a chair. Look at the overhang near your lap and along the walking route. Fold an oversized cloth neatly if that makes it easier to use. A runner is another option when you want some fabric but prefer a visible tabletop.
Keep the rest simple
Plain dishes give a patterned cloth room to stand out. Before washing, follow the care instructions for that particular fabric. Store it where it can be reached without unpacking a pile of occasional linens. An accessible cloth is much more likely to become part of everyday meals.
