I’m halfway finished with my new niece’s Prime Factorization Blanket!<\/p>\n

That’s the good news. The bad news is that it doesn’t look like I’m going to finish before Arianna arrives. But the good thing about a blanket is that it doesn’t have a size, right?<\/p>\n

I actually finished up to 49 a week ago. I did not take a picture and report my progress. And then — when I started on the next row and began knitting 50 — I discovered I had used the wrong color<\/em> when I knitted 40! I had used the color for 3 in place of the color for 5! *shudder*<\/p>\n

(Those who need to be brought up to speed, I explain the blanket in previous Prime Factorization<\/a> posts.) 40 should be 2 x 2 x 2 x 5, so the square was divided into four sections, with three of them the color for 2 (blue), and one the color for 5 (green). But, horror of horrors, I had used the color for 3 (yellow)! And I didn’t even discover it until I after I had knitted 50 = 2 x 5 x 5, also using yellow when I should have been using green! Yikes! But then I was getting ready to start on 51 = 3 x 17, and then it dawned on me that the color for 3 is yellow, so it is NOT the color for 5, and I’d been doing it wrong!<\/p>\n

Fortunately, it was on the end of the row, and relatively easy to fix. I took out the knitting I’d done on 50, undid the last white square in the row, and then undid just the yellow section I’d put on the top of 40. I replaced it with green, knitted the white square back, and then started up on 50.<\/p>\n

But I’ve decided that taking a picture after each row and *checking* the numbers carefully is a good idea!<\/p>\n

I did discover a mistake when I finished knitting my prime factorization sweater<\/a>. I think it was in the rectangle for 48. But 48 has five factors, and in that piece of knitting the factor for three only was about four stitches. So I was able to pick them out and put in the correct color with a crochet hook! It would not<\/em> be so easy to do on this blanket, so I am going to have to be more vigilant!<\/p>\n
