This specialized foot is designed for sewing alongside longarm quilting rulers, making it easy to create decorative quilting designs like lines, feathers, and circles. It accommodates any commercial Plexiglas longarm rulers with a ¼-inch thickness, allowing smooth quilting along the edges, which is especially beneficial for circular patterns. With the feed dogs lowered, you guide the fabric and ruler manually, keeping the base of the foot pressed against the ruler’s edge. The adjustable foot height lets you match it to the fabric thickness for effortless movement, preventing snags and ensuring seamless quilting.
