This quilt uses 1 package of Bali Crackers in Breakers, or 40 - 10" blue squares for the background. The squares are separated from light to dark and cut with a slight curve to give the appearance of underwater. Then you will applique the turtles, seaweed, coral and fish. What a great gift! All of my patterns have easy to follow instructions with lots of colour illustrations. The quilt measures 53" x 75" and includes full sized templates.
