What's the best foot to use for echoing? Handi Feet Echo Feet Kit

The Echo Feet Kit is a set of three acrylic feet with a ring that extends the width of the hopping foot. The feet provide a fixed interval to use when echo quilting around a motif or using rulers. The Echo Feet provide a 3/8-inch interval, a 1/2-inch interval, and a 3/4-inch interval.  Compatible with all HQ machines with Interchangeable Foot Mount.

NOTE: All optional Handi Quilter feet for HQ longarms require your Handi Quilter machine have the Interchangeable Foot Mount.  HQ machines manufactured before November 2014 may need the Handi Feet Conversion Kit installed to make optional feet compatible with your machine.
