BSR Presser Foot—The new BERNINA

®

 Stitch Regulator (BSR) is another 

option for free-motion stitching. This unique foot, available for several  
BERNINA

®

 models, makes you a confident free-motion stitcher even if  

you’ve never tried before! The BSR adjusts needle movement to coordinate 
with fabric movement. With two sewing modes, the BSR offers regulated, 
even stitches, no matter the speed or direction in which the fabric is moved.  

 

The BSR operates with a camera-like sensor that reads the fabric through  
an optical lens in the foot. The sensor “looks” at the fabric, senses the  
movement, and calculates the distance. It then directs the needle to stitch 
according to the selected stitch settings. For example, if the stitch length  
is set at 2.5mm, the sensor calculates the distance and stitch frequency 
needed to repeat stitches with regular precision regardless of the speed  
at which the fabric is moved. 

 

The BSR foot has three interchangeable soles for all types of free-motion 
work. The closed metal sole is similar to Darning Foot #9 with the needle 
centered and visible; the open metal sole is similar to Freehand Embroidery 
Foot #24,with an unobstructed view of the needle; and the large transparent 
sole glides easily over fabric, including bulky quilts (where the large diameter 
of the clear sole compresses the batting, allowing easy foot movement and 
needle visibility) and provides full visibility of the stitching area. Experiment 
with each sole, determining which you prefer for each technique and 
combination of materials you try – stitching through different types of quilt 
batting and fabrics, working with various thread weights, and sewing 
techniques such as sashiko, trapunto, bobbinwork, etc.

  

 

BSR Machine Settings—Thread the machine with the desired thread in  
the needle and bobbin and attach the BSR foot – don’t forget to plug it in! 
Lower the feed dog and set the machine for straight stitch. Select the  
desired stitch length to “tell” the BSR how long you want your stitches to be. 

 

Select BSR Mode 1 or Mode 2, depending upon your preference. Mode 1 
has constant needle movement; even when the fabric stops moving, the  
needle continues to move up and down very slowly; this mode gives the 
sewer time to stop and think about the path the needle is taking. With Mode 
2, stitches are taken only when the fabric is in motion; when the fabric stops 
moving the needle comes to a complete stop, starting again only when the 
fabric is moved. Try each mode with various techniques (quilting, sashiko, 
trapunto, silk-ribbon embroidery, bobbinwork, etc.) to determine your favorite 
in each situation.  

 

Marking Your Fabric—Free-motion designs can be stitched with or without  
a design to follow. Stipple stitching and “doodling” are often used to fill an 
area and are done without following drawn lines. Other designs such as 
feathers, wreaths, clamshells, and other traditional quilting designs can be 
transferred to the fabric using your favorite method: water- or air-soluble  
fabric marker, fabric chalk pencil or marker, or a pounce pad.  

 

Advice for beginners: For your first practice piece you may want to mark a 
design on the fabric. Start with a loose, open design that is not too intricate; 
there will be time for that once you get the feel of maneuvering the fabric.
