Italian/Kitchner Cast Off - Better than Tubular!

I'm grateful to the folks who have posted videos on the Italian or Kitchner cast off for 1x1 rib (especially, Suzanne Bryan's video) but I find written instructions easier to reference.

Here are mine:

Setup

• Cut yarn to 4x the length of the bound off edge.
• With tapestry needle, pull tail of yarn through the first stitch on the left needle (a knit stitch) purlwise, and leave the stitch on the needle. 
• Insert the tapestry needle between the first two stitches on the left needle from back to front and pull needle to front; turn Needle and go through stitch 2 (a purl stitch) as if to knit; pull tail through. 

Cast Off

• Bring the needle through the first stitch on the left needle knitwise and drop stitch off the left needle; before pulling the tail through, turn tapestry needle and insert through next knit stitch as if to purl; pull tail through.
• Bring the needle through the first stitch on the left needle purlwise and drop the stitch off the needle; before pulling the tail through, insert the tapestry needle between the next two stitches on the left needle from back to front; turn needle and insert in 2nd stitch on needle (a purl stitch) as if to knit; pull tail through. 
• That's it!
