I googled the pattern and found that it's difficult to find a place to buy the pattern. The creator sells her patterns to LQS by preference, because she likes to encourage us to buy a lot from them. The has dozens of wonderful patterns, not just this one. The link that worked for me was at
www.creativequiltkits.com (I had Googled "Stacks 3 by whirligigs" and it was listed about 5 down from the top. The author's site shows all her patterns.)
Meanwhile, the colors in the original pattern are darker than the ones in Catsden's posting. I admire the original, but love the one in this post!
