That means there are 4,372 pieces that are 1" not including the border pieces so throw in a couple thousand more and you probably have at least 6,300 pieces or more in the quilt! Congrats to you for sticking with it! Perseverance paid off! It is so stunning to look at and reflects the light beautifully! Gorgeous design from JM! Love her books and work too! Fantastic job!! :D :D
