Not like you probably care, but.
We have officially frogged Mosey, and are casting on 76 stitches this time (the right number) instead of 72. The cables will fit properly.
It's not that I can't chart my own cable. It's that part of the look with Mosey is that from the front, the cable pattern is a wide expanse of the same thing, with only one contrasting panel in the very back. To have a different one running down the middle would have changed the look substantially.
