Am I seeing your quilt blocks correctly: each block is a solid piece of gingham which has been embroidered on to produce the pattern?
You have changed my thoughts on gingham-from the dark side back to the light side...when seeing or hearing that word I usually relate it to the awful pleated skirts we had to make, in gingham, in 7th grade Home Ec (mine was orange). You have successfully pushed that picture of gingham to the back of my brain. Your quilt is really quite wonderful!
