The panels were easy to make; the hard part was figuring out the layout. I made a template for the left panels and one for the right panels and one for the valance, to guide in cutting.
(If you're looking carefully, you'll see that in the end the pattern fell on the alternate diamond in the end.)
Instead of a chunky upholstered cornice, the flat valance is made on chipboard so it's thin and sleek.
The panels were pleated on the table; plastic clips held the pleats in place.
The white silk blackout shades were trimmed in charcoal grey banding, and motorized.
