I looked for a video on this site for that stitch but didn’t find one. Maybe someone will come through for you with one. But I can try to explain it a little.
Cross 2 Front: This is the easiest. It seems weird, but it works if you just do it. As you look at the stitches you are ready to knit, skip over the first one and knit into the second one just like a normal knit, but don’t slip anything off the LH needle. Then go back to the stitch you skipped and knit it just like normal. Now slip both stitches off the needle at the same time. You made a miniture cable like twist. When you get a row of these lined up they begin to look neat.
Cross 2 Back: Do you know how to knit into the back loop of a stitch? This is what you do, but instead of knitting into the back loop of the first stitch, you skip the first stitch and knit into the back loop of the second stitch on the LH needle. Again this seems impossible at first, but just do it, and it can be done. (See below if you have not done a ktbl.) Then don’t slide it off the LH needle. Now bring the tip of the RH needle around the end of the LH needle, so that it is in front, and knit the stitch you skipped in the normal way and slip both stitches off the needle.
If you have not learned to knit in the back loop, try it on a test swatch, just doing it into the first stitch at first. I could describe it as a normal knit with this exception… Instead of inserting the RH needle tip into the front of the stitch, like you do for a regular knit, insert it into the back leg of the loop on the needle. Think of it as being like inserting the RH needle into the stitch as if to purl, but instead of on the near side of the needle, do it behind the needle (on the side away from you). Then yarn around and knit the stitch from that position. This twists the stitch.
Get someone to read these instructions to you as you work if you find it hard to read while you do it. I find that helps me. I hope this helps.
