From the indisputable Kim Stockton..
Block #41: Windmill Square.
Available here: Kim's instructions for Windmill Square
Isn't this nice :) This is one of Kim's alternate square's she's been doing up as patterns for the Krista members. This was good to hook as well. With all the lacey bits around it, it doesn't seem to come together till the final two or so rows, and then it falls into place.
This would be BEAUTIFUL if done with 50 other's and sewed together into a big square throw!
