Mercury sash, in progress.
The two photos show the first couple of stages: raw cuttings of fabric on the left, with the remains of the yardage pulled away. Two sashes next to one another. The photo on the right shows the interfacing interleaved with the fabric, ready for ironing/gluing in place.
The next step after gluing will be to sew the tails to the center sash on both the front and back pieces, and then sew the front and back sides of the sash together, with the tab tucked in side. I may not do that step tonight, though, because I don’t have orange thread.
Once that is done, both sashes will have to be turned right-side-out. The turning holes will then be ladder-stitched up, the tab sewn into place, and the whole thing ironed and pressed with an inch of its life. And then it’s done.
KevinReader, I hope you see this.
