OK ... I'll confess, I just couldn't wait and after all the discussion today about this pattern ... I dug thru my stash to find a piece with four repeats. And went at it tonight.
I'm in awe and wish I had more of the fabric. The flowers were not huge, so I kept my squares smallish at only 2-1/2" each.
4-Patch Posey Fabric
I think every square has turned out different!!!
