I judged show this week where there was one quilt with a large meandering design hand quilted. It was well done and was every effective. I also suggest using a stencil to mark the design or can draw your own to have a guide to quilt on. There are many stencils of the meandering design available. Quilters have said they start with a stecil until they get the general configuration and rhythm of the design. Also makes the overall look more consistent.
