That is seriously gorgeous!! I tried to get in close to see what kind of applique (needle turn? hand? raw edge machine? I can't tell). I don't think it was over quilted at all - I think the quilting design was just right.
I too am surprised there are no ribbons on it.
I want to add that yesterday I was at Navy Pier in Chicago and looking at the Stained Glass museum and I took several pictures thinking "quilting designs" and quite a few remind me of this quilt. Way beyond my capability but I'm glad someone was able to do it to (perhaps) inspire me.
thanks for sharing.
