Do you read Wanda's blog "Exuberant Color?" She has so much inspiration there. Take a look at this log cabin quilt. The black and white "fireplaces" are in the corners. The logs look like one-inch strips made from everything in her scrap basket. The quilt has a "streak of lightning" look.
Wanda's teaching a class on Color on July 25, so if you live near Sandwich, Illinois, you might want to join in. I wish I could shoot over there and participate. What fun that would be. Details here.
