The new 4234DT adds a professional look to your projects with serged seam finishes. Garment seams lie flatter and look better with an overlock stitch. Plus, home décor projects often suggest the use of a serger for rolled hems, secure seams and differential feed. Choose from a 2, 3 or 4 thread look and enjoy the new easy one-touch needle threader. Create stitches from 2.0mm to 4.0mm in length and 5.0mm to 7.0mm in width. The included large extension table adds extra space for handling large projects and the free arm makes it easier to sew sleeves, trouser legs and other hard to reach places.
