Very pretty blocks but that's an outrageous price for a 12.5" block! Do you know about Quilter's Cache? It's a free site that has patterns for zillions of blocks, and many different sizes. You could go to the 12.5" block page and make a bunch of lovely blocks using your own fabrics, and no $29.95 per block! Check out that site here:

These are just the 12" blocks (12.5", unfinished).
