So, I'm going to be a graduate teaching assistant next year and need a better wardrobe. I was thinking about crocheting some sweaters to wear over oxford shirts. The thing is, I don't want it to look crocheted, but just wooly. Does that make sense? Will felting the sweater make the stitches blend? Does anyone have a good pattern? I've been crocheting for more than 12 years, but I've never done the felting thing and am unsure what the purpose of it is.
