Frequently Asked Questions

What is the difference between manual and automatic buttonholes?

Manual buttonholes give you complete control over the length, allowing you to create buttonholes of any size to match your specific button. You manually advance through each side of the buttonhole. Automatic buttonholes are pre-programmed and typically sized using a button measurement or sensor.

Can I use this foot on my bernette machine?

Yes, the BERNINA Buttonhole Foot #3 is compatible with many bernette B-series machines that use 5.5 mm or 9 mm stitch widths. Check the compatibility list to confirm your specific model is supported.

How do I create corded buttonholes with this foot?

Thread a length of cord, perle cotton, or heavy thread under the foot and through the guides. As you sew the buttonhole, the zigzag stitches will encase the cord, creating a raised, more durable buttonhole perfect for jackets and coats.

What is the smocking feature used for?

By using elastic thread or cord with the gathering capability of this foot, you can create decorative smocking effects on garments. This is perfect for children's clothing, vintage-style blouses, and other projects requiring elastic gathers.

Will this foot work on older BERNINA models?

The Buttonhole Foot #3 is compatible with many BERNINA models from the 1-series, 2-series, 4-series, and 6-series that have 5.5 mm or 9 mm maximum stitch width. Refer to the full compatibility list or contact OSP Machines for help confirming compatibility with your specific model.
