These round tablecloths have been beautifully made from Mexican oilcloth. They are 68 – 70 inches in diameter, strongly stitched, and hemmed on the perimeter with special fabric bias tape. The center seam is stitched so it lays flat on the table. If you want to calculate your overhang, subtract the diameter of your table from 68, then divide by two. This is the number of inches of overhang you would have on any side of your table.
