Bernina Patchwork Seam Guide

The BERNINA Patchwork Seam Guide is a precision sewing accessory designed for quilters and sewists who need consistent, accurate seam allowances every time. It mounts directly to the bed of the machine to the right of the feed dog and glides along the fabric edge to keep seams perfectly straight — whether you are piecing a quilt block or hemming a long length of fabric. Compatible with BERNINA 5.5 mm and 9 mm machines, it pairs especially well with the BERNINA Patchwork Foot #37 for a complete precision piecing setup.

Does this guide come with the BERNINA Patchwork Foot #37?

No, the Patchwork Seam Guide is sold separately from the Patchwork Foot #37. However, the two accessories are designed to work together as a system for precise quarter-inch piecing, and BERNINA recommends using them in combination for best results.

How does the Patchwork Seam Guide attach to the machine?

The guide screws directly onto the bed of the machine to the right of the feed dog. The sliding guide rail can then be positioned flush against the edge of the presser foot or set at a specific distance to achieve your desired seam allowance.

Is this accessory suitable for beginner sewists?

Yes. The Patchwork Seam Guide is straightforward to install and use, making it a practical tool for beginners who want consistent seam allowances without marking every piece of fabric. It is equally valuable for experienced quilters who piece at high volume and need reliable accuracy.
