Welcome to the Quilting Board!
I would pick #3. I like the way you put the lightest one in the center and the darkest ones in the outside corners. JMO
Is your plan to make three quilts from these beautiful blocks? If you're making one long, narrow quilt, I like number 3 the best. It looks much more balanced :wink: Otherwise, I think I would be tempted to use more of the blocks and make one larger quilt. How's that for about 2 cents worth of advice? :? Anything you do with these blocks is sure to be beautiful. They are so colorful, and I love the designs used. :thumbup:
Number 3 gets my vote.
I love them all! Cannot possibly choose from such lovely blocks!! Well done.
