How to: The Tubular Bind Off
The tubular bind off goes hand in hand with the cast on of the same name. Ideal for 1x1 ribbing, it leaves no ridge and therefore conforms to the ribbing. The movements for this technique happen repeatedly over four stitches.
To begin, cut the working yarn, leaving a tail approximately three times the width of your finished piece of knitting, and thread the yarn onto a yarn needle.

Step One
Draw the needle and yarn through the first stitch from left to right knitwise and drop the stitch off of the knitting needle.

Step Two
Insert the needle from right to left purlwise into the second stitch on the left knitting needle.

Step Three
Now back up and insert the needle from right to left purlwise into the first stitch on the needle and drop the stitch off of the knitting needle.

Step Four
Finally, draw the needle through the second stitch on the knitting needle knitwise from the back side. This can be accomplished in two steps by doing the following:
1. Draw the yarn in between the first two stitches from back to front.

2. Insert the yarn needle knitwise through the second stitch.
Repeat from steps One through Four until all stitches are bound off.
