I have been there before myself and am that way right now on a quilt as well. Sometimes we 'creative ones' need to turn our attention and creative minds to another project for awhile, we can get bored with the simple things and need stimulation. Catch a quilt show helps, the change of pace will help as will switching projects. If we feel we 'have to get it done', it becomes 'work' in our minds eye and work isn't fun usually.
