Okay, this is theoretical, but there's something I want to knit that's a pretty flat shape, but it does have some shaping to it. I am wanting to know how to retain that shaping but adding more sts per inch. It's a baby bunting that has enclosed feet. It's usually made with super bulky yarn, but I think thats too hot for south texas. So I want to decrease the bulkiness and add sts with smaller yarn.
