Get back on the needles
My personal philosophy is this: once you discover your mistake, frog at once. Then, get right back to knitting and knit back to where you were when you found out. I had the opportunity to live through it this morning, when I had to frog my Kabuto hat not once, but twice. Apparently I can't read, and apparently I also never look at my knitting, because I suddenly realized I'd been decreasing for 30 rows when I shouldn't. Yeah, it was fun. Not.
It's like riding a horse ( or so they say...); if you don't try again immediately you will never ride, um, knit again.
Well, you will probably knit again, but it's not going to be this WIP. The abandoned, somewhat frogged WIP is doomed never to become a fully realized FO. You don't want that, do you? It's bad karma. Only worth risking if you really hate your knit. Then it will turn into a dung beetle in the next life instead of you!
