I think I know which one you mean. The problem is someone reposted the photo & said it was a SAS, and although it shares some design elements with that pattern, it's not. So if you do a search on SAS you won't find it.
Here's the original post.

If you turn the picture 45 degrees, you can see it's plain square blocks of the toile, with pieced sashing and a square in square cornerstone.
Is this the one???
