Looks pretty simple - 2.5" strips of the dark and the white made into 4-patches and then 2.5" strips of the dark separated by a 5" strip of the floral which sewin together and then are cut into 2.5" pieces vertically. Then 2.5" strips of the floral cut into the length to fit across the ends of the 4-patches. Nice block, but no idea what it's called.
