Picot cast-on video tutorial?

I having a difficult time figuring out the Picot cast-on. The pattern I’m trying is for the raspberry hat from this free pattern posted at The Garter Belt:


I’ve managed to learn most stitches/techniques from knittinghelp.com, though, and I’d love to see a tutorial on the Picot edge CO technique.

Can’t find a vodeo but this might help

Lucy Neatby’s Knitting Gems 1 covers picot.
