Well--the consequences of blithely knitting away on aran cardigans in the car is that Mistakes Are Made:
The section along each side of the back is a 4-row checkerboard. And the edge section for the front? 2-row moss.
When I realized the mistake after finishing the right front, I decided to do it again for the left side. Because it contracts more than the checkerboard, the fronts seem much shorter than the back--but I think this will block out without a problem.
Now the question is, what should I do on the sleeves? Right now I am planning to switch back to the checkerboard. Any votes?
But then, you know, I plan to knit in the car today. Maybe I'll do one of each....
