I think Ami Simms has pretty much moved on. She still has a website. The I spy and Memory quilts are mentioned in the books section and that's about it. The websites listed in her books no longer exist or, at least I couldn't find them when I looked a few month ago.
We have an I spy swap group on Yahoo that has lots of quilt photos in the files. I think you have to be a member to access them, though.
