Rarely do I do a real swatch. Often times my projects are small enough that I just cast on and knit a few inches and measure my gauge. But I've decided to knit Anne Hanson's "Twisted Henley" and rather than put a sweater's worth of knitting and find out that it's just not going to work. So here is my four inch swatch. (Just like Anne did with hers, I actually copied her from her blog). I think that it will work.
