Kalamazoo Quilts: Thanks for the heads up. It sounds like fun. Not only do I have lots of blue, yellow and neutral fabric, I just went wild (for me) several weeks ago buying a number of light fabrics that include both blue and yellow.
I am still thinking about doing the Laundry Basket Quilts mystery using blue, yellow and white (instead of blue and white, as suggested). LBQ starts earlier than BHs, so I may just wait and see how it all plays out.
