Framing A Flower by Aurora Suominen.
I used an "H" hook. The square was 6-1/2" when finished by me. I used Impeccabble Worsted in Summerset Ombre, Fiesta Ombre in Red Heart Mill Ends. This was an easy square to make. I whipped it out in a couple of hours. I am sure it would be less time for most people but I crochet slowly.
