"No brown downtown" here, if I can help it. THat said, there are some deep chocolate browns, some saddle browns, and caramel bolts I've loved to look at. But to buy and use? Not unless I'm making a quilt for someone who loves it. I just finished a log cabin quilt for my sister in November which turned out really well. She loves all things "horse brown" and woodsy.
The other color is purple. I have very little in my stash. Oddly it was my favorite color once upon a time. But now I avoid it. My purple pieces must lay in the fabric drawer sulking, wondering what in the world they did wrong that they get no attention.
