Twin needle capability
Two needles in one shaft, this allows the user to use two different colored threads. It is great for top stitch accents.
Also great for hemming jersey fabrics. With a straight stitch on the machine, on the front side of the fabric you’ll have two parallel stitches while on the back there is a zig zag stitch, so the seam will stretch with the fabric.
It can be used with any machine that sews a zig zag. Select the stitch, then hand turn the wheel at first gently, to make sure it can be sewn with a twin needle.
