I know you only got your Dad Scarf in March, and now it's totally summer where you are. So you're probably not using your scarf at the moment. But it just occurred to me that, reading my blog post about it, you might have wondered why the picture of it looks so nice and flat when (in all likelihood) by the time the present reached you in the mail all my careful blocking had been undone and it looked more like a tube.
A valid question.
So I thought I'd share a link that discusses just such an issue, in bountiful detail! TECHknitter's explanation is also a great example about why TECHknitting is one of my very favorite knitting blogs. So mathy!
Thought you'd enjoy.
P.S. Dad -- if it's really unwearable, I can try to block it for you again. Let me know next winter ;)
