Place fabric face down on the table top. Add twice the fall on each side. The fall is the distance from the top of the table to the bottom edge of the table top. Cut out the table cloth.
Pin the fabric corners to fit the corners of the table (the fabric should be face down on the table). Sew seams along your pin lines at each corner. Trim away excess fabric at the corners.
Turn the raw edge under 3/8 inch and then turn the fold under 3/8 inch and sew all around. Cut four pieces of 1/4-inch elastic 6 inches shorter than each side.
Fold the elastic in half to find the center. Tack the center of the elastic on the inside of the double hem half way along the side. Stretch the elastic toward the corner and sew the stretched elastic from the center to the corner. Repeat for the other side of the elastic. Repeat for each side of the table cover.
