I salvaged what was usable of the main fabric, and Kim Freeman worked with the homeowner to choose a coordinating fabric and trim. Samuel and Sons' amazing skinny lip cord in blue defined the line between the main fabric and the bias checked band.
The original curtains were ambitious, but much had gone wrong. Banding around 3 sides was trimmed with lip cord with the lip removed and applied with visible hot-glue. The mitered check did not match anywhere, and attempts at repairing it with hand-stitches were obvious. The pleats were not sewn; a slip of buckram was tucked into the back with a single tack. Interlining had been roughly cut, unhemmed, and didn't reach the face fabric hemline, which, incidentally, was topstitched, unevenly. The lining hem varied from 1" to 3" and was crooked. Masking tape had been left on on the wrong side, and left orange stained stripes. To top it off, one panel had been made upside down!
Once the panels had been dismantled and cut evenly, banding was needed to add to the length. Skinny lip cord edged the top and bottom, between the face fabric and bias checked banding.
Two-finger pinch pleats are pleated to the check pattern, rather than the print, because the floral motifs were unevenly distributed across the width. I love fat, interlined pinch pleats! The pleats are tacked invisibly, at the lip cord, with blue thread.
Underneath, an inside mount flat Roman shade, French blackout lined, is trimmed in the same lip cord and bias band.
