Morning after? No hangover.
Nothing like popping into the kitchen the next morning, looking at last night's work, and saying ... yes. That will do.
Each plate will have a double line of quilting, one line each ¼" inside and ¼" outside the inner ring. I'm also tracing each petal roughly ¼" inside each seam. Later, when more of the quilt is stable, I'll go back and add the decorative motifs in the empty circles inside each plate, and in the empty spaces between each plate.
Right now? This is triage. This fabric is strong but it IS nearly 80 years old. I don't want to handle it any more than necessary until it's got the extra strength of the batting and backing helping it out.
