When working through a "creative block" I often turn "back to the basics" and that helps me power through creative slumps. One of the ways I do this is to slow down, and really work on the "process" of quilting.
This may mean slowing down my piecing, and really get my seams and corners to match. This may mean slowing down my free motion quilting and make nice deliberate designs instead of powering through it. This may mean slowing down the design process, and crating fully formed designs before I even start.
Whatever the slowing down process you choose, use the time you add to enjoy the process. Have soothing music on to help calm the mood. You may find that even the parts of the art making journey that you didn't like before will end up with new appreciation!
