Melody Johnson. I like the skinny lines and the dots and the colors and, most of all, I love how it looks lit from within. I found a blog entry from around the time she made this piece. She had been feeling stuck and making these little quilts gave her a sense of fun and freedom, which is what you need to be unstuck. She writes about it beautifully here.
I am crazy for things that look lit from within, which is different than just light and dark.
Colorwash quilts have a lit from within look, too. Wanda from Exuberant Color does an amazing job making that happen in her color wash quilts (and in other types, too). Here is a type she calls confetti (because it is made from small scraps).
