Double Knitting: invisible bind off

To match the invisible cast on you will have to make a kitchener stitching at the end of your work. Separate the stitches in the front and back onto two separate needles.
Cut yarn and make one tail long enought for stitching, i.e about 3 times the width of your work. Put the long strand on the darning needle and the other strand will be weaved in later. We have a separate Drops Video for Kitchener Stitch, but this is how you do it:
Stick darning needle pwise into 1st st on 1st needle and pull through without dropping st off needle.

Stick darning needle kwise into 1st st on 2nd needle and pull through without dropping st off needle.
* Stick darning needle kwise into 1st st on 1st needle and drop off needle, stick darning needle pwise into 2nd st on 1st needle and pull through without dropping st off needle.
Stick darning needle pwise into 1st st on 2nd needle and drop off needle, stick darning needle kwise into 2nd st on 2nd needle and pull through without dropping st off needle*
Repeat *-* across
