Okay, I'm knitting Petunia the Piglet from Bernat's little booklet of four animals. At one point, I will have 25 sts on my needles. The next line reads (P1. M1P. P11. M1P) twice. P1. 27 sts. I've gone over the math in my head numerous times, and it keeps coming out to 29 stitches. I am then instructed to P1, M1P, P12, cast off center st, P12, M1P, P1. In other words, the pattern keeps going assuming I have 27 stitches on my needle instead of 29. The rest of the pattern has me steadily decreasing each side until it ends.
All progress on the piggy is halted because I'm dithering over whether I should cast off the three center stitches to make the other numbers correct or whether I should ignore the incorrect numbers and just have the pieces a wee bit wider than the pattern seems to specify. Which should I do? Is one or the other likely to dement my piggy beyond repair? Have I simply lost all ability to count and am worrying over nothing?
