This is my new favorite knitting pattern.  Unfortunately, it can't be made very big.  I uses finer yarn and smaller needles on the purple one which made it smaller maybe for new born to 3 months.  Then on the aqua and white I used heavier yarn and larger needle to make it fit more like 6/9 months.  Wish I was clever enough to know how to increase patterns to be bigger!!  The hat is a little beanie pattern I had and I added some seed stitches to it to tie it into the sweater pattern.  Very fun to make!!!  I think our new great nephew will be getting a few of these in different colors.
