Try using stencils and Golden Threads tracing paper. Available at your LQS, the paper comes on a roll in 2 widths. Trace your design on one piece of paper, stack up to 10-15 levels of paper, then stitch the design with a 14-16 needle (to make larger holes) without thread. That gives you multiple copies of your design. Pin the copies on your quilt where you want the design, then, using your free motion foot, stitch the design on your quilt.

On my current quilt I used one stencil to do the borders and another full-page stencil for the overall design. Easy and faster than trying to draw on your quilt. Because the paper is slightly heavier than tissue paper it's easy to rip off when you're finished stitching.
