This is the "fun" part, which really means the most challenging and creative part: blending the golden goose feathers up into the pleats of the robe, and making it all somehow work.
I am happy to report the the back pleats, where the rooster feathers emerge, look fantastic, just as I had hoped. Now I am meticulously stitching in the goose feathers, which involves punching holes along the quill with a hammer and small nail, since they are so thick and tough that the needle doesn't want to go through.
The effect of the gold "wings" emerging from the pleats. More will cascade down from nearer the cross piece at the bust.While some problems have been fixed - shortening the brown taffeta hem guard to remove the train - other problems have cropped up, such as my forgetting in California the extra cream taffeta to make the cap sleeves from. The robe will have to be sleeveless. Not the end of the world, but not exactly as I'd wanted it. I must then finish the armholes with bias tape...at some point here in the next two weeks!
