This very fine white linen pressed beautifully. After the whole tablecloth was ironed, I marked out the exact finished size plus 1.5" for the board, then cut it out carefully, leaving the perimeter intact because..... well, just because I couldn't bear to cut into it.
Because of the openwork areas, it was easy to see the grid of the table behind the fabric. That made the layout easier.
2" French cotton grosgrain ribbon was adhered to the back with Sealah tape, then pressed around to the front, mitering the corners along the way. From the front, the ribbon was topstitched all around.
A length of Rowley's weight bar tubing was machine-sewn 3" above the top of the ribbon, the stitching ending right before the ribbon, with an extra couple of inches left at each end.
The fold created one permanent pleat at the bottom, even when the shade is fully lowered; the extra fold hides the weight bar pocket stitching, and any other clutter that might show through the open areas.
This project was right up my alley! Thanks Monica, I'll do this again any time!
