Oh I love that pattern!
Cables pull the fabric “in” (think ribbing) so if you did several of them you might have to adjust the pattern a bit. However, adding a single cable would be easy and wouldn’t affect the pattern very much.
Just take any simple pattern (top down would be easiest of course) and do the neck stitches whatever they may be and then calculate where the center would be. An even number of stitches on the front would make it center better so add one if you need one right after the neck stitches. (or add a few more to make it even if you want a larger cable.)When you know where center is figure out how large you want the cable and then add to that a few stitches on either side done in purl stitches so the cable will stand out (it’s done in knit stitches).
There are always rows between the twisting and the number of rows between makes a very different looking cable. If you put fewer rows it makes it more of a twisting spiral, a lot of rows and you have a flat area between the twists.
I suggest you do a few swatches since you have time and test the yarn and cables to see what you like best.
Amy has a video I think and here’s another link that might help you get started. Cables are easy so have fun!
I haven’t done this btw, but it seems pretty straight forward…and now you have me want to try it.:teehee:
