Here are the written instructions.
VERY LOOSE Cast On:
It is so loose that you can use the smaller circular needle to cast on.
This is a Cable Cast On with an extra knit stitch worked between each cast on stitch and is worked as follows:
Make a slip knot and place on Left needle. - 1 stitch on needle.
Insert Right needle into slip knot, wrap yarn around needle and pull through, place resulting loop onto Left needle. - 1 stitch cast on, you now have 2 stitches on needle.
*Insert Right needle between 2 stitches, wrap yarn around needle and pull through, place resulting loop on Left needle, knit this stitch and slip off needle, replace knit stitch onto Left needle. - 1 more stitch cast on; repeat from * until number of desired stitches cast on.
If you try it let me know what you think.
