With 15 stitches, it provides a compact set of stitches that allows you to do all types of overlock sewing. It is easy to thread the looper and needle by following the coloured markings on the bernette Funlock 44. The knife drive is from below, so the stitch widths can easily be adjusted with one hand. The bright LED light also provides good visibility. And the b44 is quick, sewing up to 1300 stitches per minute.
