Dithering

I'm stuck. Is this Quilter's Block? Is this time change? Is this avoidance? I am in the middle of a wonderful reread and reluctant to leave my characters (it's 1942 in London - you know the story...) I want to get a couple of pieces done for the Art quilt class at quiltfabric.com. I kind of know what I want to do for these wall hangings, and I have everything I need. One has to do with lots of concentric circles. The other is a photo collage - I even took my camera with me on my walk this morning. Yet, I never went into my studio today. Perhaps tomorrow.
