Use this foot for all work using forward feed or reverse feed stitches.
The sole of the foot has a slight indentation both in front and in back of the needle, allowing the free passage of the thread while reverse motion stitches are formed. This promotes balanced stitch formation where the fabric is moving back-and-forth while reverse motion stitches are formed. Owners of 9mm rotary models 1630 and 180 should consider using Foot #1C (9mm), which will better match the wider feed dog on these models
When purchasing feet, please select which version of foot which fits your machine. The ‘standard’ version of foot fits older machines from the Bernina 910-1630. The ‘v version’ fits the newer Bernina machine models from the Activa 125 upwards.
