I know there is a way to search those mysterious photos, Janice McC, but I don't know how. None the less,, that is an intriguing but simple pattern. Squares and HSTs on point. Perhaps someone else knows the trick to search the source/link for us or we can be creative and try it ourselves. The blocks look larger than 2.5" but why not with our little candies. It would work.
Thanks for the photo. Looks like a fun way to use up our stash of 2.5's.
