book:Cable Needle Freedom, Any Ideas?

I was looking up the Sweater Wizard and the Stitch and Motif Maker software, and this book was in the same section as them. I am curious that if anyone has this book and tell me about it. It will be great if we can knit all cable patterns without a cable needle. Is that doable?

I knit all of my moderate sized cables without a cable needle. Anything up to a 6 stitch cable (others are possible too I just don’t know how), and you don’t need a book to learn how to do it.

And a slightly different method

Hey, you offered very valuable info for me ! Thank you so so much !
