Janome has a great foot called the Border Guide foot. It’s great for sewing multiple rows and keeping them straight and evenly spaced. So far, I’ve used the foot for embellishing fabric to use in applique, for heirloom stitching, for quilting, and most recently, for making lace!
The secret to the border guide foot lies in the red guide marks. The two sets of vertical red lines are calibrated to allow perfect spacing of rows. The horizontal red line matches the needle drop so you can line up the start of each row. The small red mark denotes the center of the design for lining up with the marking for the first row.
