This embroidery needle offers a different method for stitching your work! The process works much like a punch needle tool would, albeit with the thinner strands of embroidery thread instead of yarn.
Using 3 strands of 6 strand embroidery floss (or a similar weight), you thread the needle and make your stitches by 'stabbing' through the fabric at regular intervals. Depending on the final look of your project, you can use either side of your finished work.
