Someone has contacted me requesting help identifying the possible origin of this piece of embroidery and a possible date for its working. I have my theory but I'd like to see what other people think. Please leave comments with your theory, (with citations of possible sources to support your theory if you have them). If you know of similar pieces I'd love to hear about them!The roundal is about 8 inches in diameter and appears to be some sort of pattern darning. You can see very good detail in the last two images if you click on them.
