Bernina Sewing Machine #86 Ruffler Foot 5/7/8 SeriesBernina #86 Ruffler Foot Series 5 7 8 Ruffler #86 is a specialist in the simple gathering and pleating of fabrics. Thanks to its variable setting options, both pleat depth and frequency of gather can be varied. This means that Ruffler #86 can set a pleat with every stitch, every 6th stitch, or every 12th stitch, as you choose. There's also the option of sewing without pleating, without replacing the presser foot (ruffler setting = 0).
