I made a whole lot of progress, and was pretty darn pleased with myself, until I noticed a small problem. Do you see it? I got off on the berry stitch section in the middle.
I originally caught the mistake about 7 rows after I started it, and figured out what had gone wrong. I corrected the problem, and then decided that I could live with the mistake. After all, I didn't have time to waste the time required to fix it, right? I'm knitting a freaking cardigan in 17 days. Time is valuable. This is supposed to be a challenge, and I would find it challenging to leave the mistake there. So, I left it and knitted on for about 20 more rows.
The error mocked me all night long. I even dreamt about it (I wish I was kidding). Finally, after a non-knitter pointed out the mistake and asked if that "ridge" was supposed to be there, I decided that I couldn't ignore it. Cue me dropping down 32 rows to get down to the beginning of the error. I'm kind of proud of myself for actually doing it. Now I just have to get back up to the top. It's taking a long time, longer than knitting the pattern takes. If only I had recognized that I would not be able to live with the mistake and had corrected it when I only had 7 rows to fix.
