Here's a small sampling of the swatches I haven't ripped out.  I wish I'd kept the other ones even though I knew I wasn't going to use them. 

The peach ones are Bali, white is Cotton Ease, and the blue is Jaggerspun Zephyr.  I know I don't like the bottom left one.  Partially because it should have been done on a smaller needle.  Zephyr isn't machine wash and dry, so it's out.  The Cotton Ease isn't too bad but I'd rather use a smaller gauge yarn.  The Bali is the softest of all the yarns I've used and it meets the machine wash & dry criteria.  I'm deciding between the middle two swatches.  I started the one on the middle left with a larger needle then switched to a smaller one, which I like the look of a lot better.  I like the middle right too because it's more interesting but I'm not sure how a whole baby blanket would look with it.  It probably would've helped if I'd make it bigger but like I said, I'm tired of swatching.  Decisions decisions!
