I found the photo of the William and Mary wall mosaic at the National Gallery in London on Flickr with a creative commons license. Still, I decided to contact the photographer Matt from London, who replied, "I'd be delighted for you to include the photo on the quilt. Thanks for asking."
My mind jumped to London because Eliza's husband was British, and the lack of child custody rights for women were similar in England and the United States. I added the George Washington stamp print - a free-to-use internet image - for Eliza's step-grandfather. The beautiful striated green fabric is another hand-dye by Vicki Welsh.
I took a photo of the group of blocks today.
I'm pleased with how the greens and yellows work together, and with the mix of bright and subdued prints.
