Fold the circular tablecloth into quarters. Use binder clips to keep it from shifting. Katie used these rather than pins so she wouldn’t make holes in the fabric. Clip the string to the center point of the tablecloth, the corner of the folds (at upper left in photo). With a marker or chalk, use the string as a compass to mark the size of the tabletop. Keep even tension on the string as you pull it across the tablecloth. Cut all layers along this line. You’ll end up with a smaller circle.
