I was doing a gauge swatch last night and the instructions specified stockinette stitch. I had already purled half a row where it should have been knit, so there was this weird rib where it should not have been. Watching TV then, I purled an entire row that should have been knit. I guess I just get into things and forget where I am.
So I pulled out that row and tried to reinsert my needle, but I dropped a stitch about halfway across, and got frustrated and frogged it all back to the beginning and started over. If it had been further along a major project, I probably would have messed with reinserting the needle and picking up the dropped stitch and stuff, but it seemed like less work to just start over at that point.
Now seriously, it was a gauge swatch. A row of bumps would make no difference at all in measuring how many stitches or how many rows. It's just that that half row rib had bothered me every time I came to it, and I knew I wouldn't be able to stand another whole row in addition. Am I just too obsessive or what?
