Phooey, I didn't do a gauge swatch

I've not done a gauge swatch on this Brown Sheep Superwash Worsted yarn. I KNOW that will bite me, but I've not done it. Suddenly I realize that, based on other time I knit with Brown Sheep Superwash, this project could GROW! At which point, it may be ridiculous. So, I'm waffling. I think I'll start a swatch tomorrow on another skein of yarn and see what transpires. After all, I don't want to frog any more than I have to! sigh
