He looks so snug and cosy in that lovely cardigan! And didn't you knit it up quickly too. That's why I love knitting for my baby granddaughter - little garments take no time at all .
Another great resource for knitting patterns is Etsy.com (not free, but very reasonably priced instant PDF downloads). I've bought several patterns from them when I've been unable to find what I wanted on Ravelry. Also, if you are considering the paid for patterns on Ravelry, it is worth checking Etsy to see if they have the same ones. I found one yesterday that was £3.60 on Ravelry, but I downloaded the very same pattern from Etsy for £1.19
