that swatches lie. It's just that normally knitters find that out at the end of the project, when something comes out unexpectedly huge, or tiny. With the Vitamin D I'm trying to knit, I found it out at the swatching stage. Here's my swatch:
Top half is on 3.5 mm needles. Bottom half is on 2.25 mm needles. Both have the exact same gauge, and not the one for the pattern. And I don't want to go up a needle size, because the fabric is already verging on loose. After I washed it it got tighter, but it's a not too big swatch and the cardigan is large, and it will pull down and I'm hesitant to to go up a pattern size, although I would rather this ended up a little loose, than hugging my CrossFitters shoulders, like everything else I make. Ahh decisions, decisions.
