I definitely won't be putting them side by side like this. If I'd thought to make an equal number of opposite 9-patches (switching the placement of the lights and darks), then I'd consider setting them side by side.
Here are a couple of looks I like and am definitely considering.
I just made this one up. I had made a similar stack of 9-patches with Kaffe Fassett leftovers, so I stitched this up and consider it a free quilt. It's not very big, but that is the beauty of this sort of thing. You make it as big as the number of blocks will allow.
Happy Quilting, Friends!
