The freemotion border design Tip Top is a design constructed out of loops, big teardrops. and some straight lines. The playful design looks nice on its own, but it can be doubled for a wider border. It goes well with a themes like candy, butterflies, bowties, bows, children but would suit just about any quilt because of the mix of straight lines and round shapes.
The blogpost contains a written description with a picture tutorial about the stitch path and structure of the design. There is a link to a longer normal speed FMQ YouTube video of a domestic machine and a link to a short animated drawing.
