Well, friends, as of this afternoon I'm 6 inches into the body of the sweater. I've just joined the second ball of yarn. I have only 4 balls. I'm a little worried that I won't have enough yarn to finish the hood. I thought 800 - 900 yards would be plenty, but I'm not sure now.
If I get further in and it starts to look like I really won't have enough, then I'll just have to rip it all back and start over again in a smaller size and/or larger needles. The size I'm knitting now will give Rose 7 inches of positive ease, which is a lot, but she's a kid, and I like to give kids lots of room to grow. I don't like working hard on a sweater only to find she's outgrown it in 3 months.
So. If I have to rip back and start over again, I won't succeed at my Knitting Olympics goal, but at least sooner or later Rose will have a complete sweater.
