After a somewhat rocky start, I am glad to say that I cast on for my Mr. Greenjean's sweater this afternoon!!!!!
I had trouble with the set-up row and could not figure out how I cast on the correct number of stitches, followed the pattern I had originally printed out, but still ended up with the wrong number of stitches! I went back online after dinner and, lo and behold, there had been a change made to the pattern in the interim. I cast on the stitches again, started the set-up row and it was smooth sailing from there.
I will post a picture tomorrow when I am further along.
