Many different accessories are included when you purchase a BERNINA sewing machine, such as presser feet or soles (depending on the model), bobbins, seam ripper, brush, and oil. Presser feet or soles are usually required for general sewing work, such as zippers, buttonholes, or blind hemming. They are included in the delivery package with your BERNINA sewing machine, depending on the model. Another useful accessory is the freearm slide-on extension table. It expands the sewing surface, which makes working on large sewing projects or working with difficult materials significantly easier. Freearm slide-on tables are sometimes included in the delivery and sometimes are available as an optional accessory. Freearm refers to the exposed part of the sewing machine arm. This is the area that also has an open section underneath so that you can work on closed items, such as trouser legs, sleeves, cuffs, or even smaller items like children's t-shirts.
