Black and White Greek Key

Our first shade of 2018 featured a graphic white-on-black Greek Key:

The miters started with a paper template.  A test corner was folded, pinned to shape, sewn, and tested.

The corners were trimmed and angled in closely at the tip, like a dart in clothing.

They were pressed carefully....

and a dab of glue was applied at the points to hold down any stray fibers.

A little more pressing manipulates the miter into square.

We chose to apply this trim using Dofix Bortenfix tape.  The tape was trimmed to size with a rotary cutter.....

then applied to the back of the Greek key tape.

Blue painter's tape marked the finished size and provided a guide for applying the trim.

The sides and bottom were folded and pressed along the blue tape, and then the shade fabrication continued as usual.

The first row of rings started 9" up to allow the Greek Key shape to show when the shade is raised.
