The panels are two-finger Euro pleats with 6" buckram.
The shades are a very sheer voile, mounted on very discreet frames that blend in with the woodwork.
Making those frames was the biggest challenge of the project. There was a lot of trial and error. I chose to use FirmAFlex for the arched part. It's white and I hoped it would blend in with the wood, but in the end I covered it all with fabric after all.
The first template was made from paper, and then a second template from foam board. I wanted something that was rigid, to fit into the space without flexing, for testing; but also a material that I could modify if corrections were needed.
John rigged up a way to stabilize the sheets of FirmAFlex so it could be cut with a jigsaw.
The narrow edge became the front. All the surfaces were eventually covered with fabric, hiding the little angle iron, the raw edges, and the joins. In the window, the frame just disappears and looks like the woodwork.
When the shades were fabricated, the ladder tape stopped just above the board line, and I ran a line of basting thread along the board line as a reference for stapling later.
I'm getting ahead of the story now, but here, the shade already stapled on and hung on a Workroom Valet, you can see how the basting line guided the fabric placement.
On installation day, our talented installer Mario dressed the draperies to perfection.
In order to get the pleats and spaces right, I made mockups of the stripe and marked everything before trimming down the widths for joining.
In the adjacent dining room, two-finger Euro pleat panels are drawn to each side. Sheer relaxed shades under the panels are just like the living room shades, minus the arch.
