BERNINA #72 Adjustable Ruler Foot.
This foot allows you to sew along longarm quilting rulers to create decorative quilt designs such as lines, cirlces and feathers. Any commercial Plexiglas longarm rulers with a 1/4 inch thickness can be used. The height of the foot's sole makes it possible to quilt along all the edges of these rulers.
With this technique the feed dog is lowered and the fabric with the Plexiglass ruler is guided manually with the base of the foot resting against the edge of the ruler. Due to the adjustment dial the height of the foot can be adjusted to match the fabric thickness individually so that the fabric can be moved smoothly. This additional option provided by the adjustable height extends the scope of applications for BERNINA sewing machines without the function of 'automatic presser foot pressure/presser foot height.
