Add a professional look to your next project with finely overlocked seam finishes. Garment seams lie flatter and look better with an overlock stitch. Plus, home décor projects often suggest the use of rolled hems and secure seams. Choose from a 2, 3 or 4 thread look and enjoy the new easy one-touch needle threader for threading two needles. The 4234D features two needles with a differential feed ratio of 0.7 to 2.0 for improved stitch quality. Create stitches from 2.0mm to 4.0mm in length and 5.0mm to 7.0mm in width. The optional 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.
