Double knitting

Hi everyone!
I recently started my first double knitting project. I’m a bit confused when you switch from knit to purl are you supposed to twist the yarn a certain way? I realized a few rows in that its not staying together on the sides. At the last 2 stitches of every row it says to slip one knit wise with the yarn in back then slip one knit wise with yarn in front then switch to the other side.

Thanks any help would be greatly appreciated!

I’ve used the first edge method suggested here but both sound good.

Give them a try and see which you prefer. You’re right that you need to connect or cross the two yarns in some way to connect the two sides of double knitting.

Thank you sooo much for this video!
