My knitting is a little like that today. Backwards. I just spent the last hour taking apart a row to sort out a problem, and then I took apart another row and found it. It was so incredibly silly an error and the error was made 3 different ways across each row, but ended in the same result each time. And, that result looked close enough to what the pattern showed I should be doing that I did not catch it.
None of this sounds like that much of a thing unless you know that there are 14 repeats of the pattern across the row of stitches, which means I made errors in each of 14 patterns without even a blink of an eye.
Unlike Marcus who walks forward with his eyes open, I knit forward with my eyes closed.
