When your heart is sad and you don't want to deal with a project, put it aside for a while. Eventually you will pull it out and deal with it, when your heart can take it. It may take a few months. I know. After three months I took out a 3'x6' quilt I was working on and finally realized why it looked so bad. I had forgotten to include the sashing. I'm working on that as well as a few other projects.
