A Consistent Mistake

I got to the bottom of my troubles with the right front of Sam last night. While watching Monster I cast on and knit the first two rows about ten times. Each time deciding it was wrong and ripping it out. What I finally realized was that I was doing it correctly--but had done it wrong on the left front. There is supposed to be a column of garter stitch up the front where the zipper gets placed. I had unconsciously switched to k2, p2 instead of k4, (k2, p2). Aha! So do I rip out the entire left front? I've decided, given that I'm sick to death of this sweater, that I will repeat my mistake on the right front. Because, after all, a mistake made consistently becomes a design. At least that's what I'm telling myself.
