Two-color Cable Cast-on (continental)

Two-color cable cast-on, with two changes to the regular method: first, I’m making the slipknot using only one color, and second, I’m picking up the yarn every time from underneath the other color. The latter makes the yarns twist around each other, so if you intend on casting on more than a dozen stitches, it’s more convenient to pick up one of the colors from over the other color.
On the video, the green yarn represents the yarn with which the edge stitches of the shawl or other knitted item will be worked. (Video only, no audio included.)
