I just finished a wolf panel with borders. I used some darker pinwheel blocks in it for interest and lots of borders and made a full size quilt using small woodland flowers, leaves, and tone on tone fabrics for variety. It looks like you are looking through a forest and seeing the wolf baying at the moon. Absolutely beautiful and not a lot of work. Since your panel runs horizontally you may need extra borders or blocks at the top and bottom to get a real "quilt" size and shape. Draw some outlines on paper to make a plan.
