That is so beautiful, and it has soooo much work in it you must be very proud of it. I would be.
I do machine embroidery also. But I haven't had the nerve to do a quilt yet. But I did buy a pattern from Cactus Shak Embroiidery called "Vintage Western" by Betty White that is embroidered on your block then you slide your batting and backing under your embroidery and it does echo quilting around the embroidery. It's a quilt as you go. you might want to check them out.
