Take a look at dottie dodge's link at
http://www.northwestquilters.org/bom.html. If you are a visual person, the blocks shown for months December and June might help you to picture how to place the colors. But they have 2 prints with only one background. The original tutorial given for this swap at
http://sewwonderful.blogspot.com/201...o-9-patch.html didn't address the layout for 4 prints... so Jane provided the example in post #2. It's understandable that wannaquilter and jaba each made the block differently-- it's a little confusing! :-) Jane's example shows both sets of diagonal squares being treated the same way. ...It's even confusing to me to explain it! Hopes something helped here. :-p
