Here's Guppy, a reworking of a design that I published a couple of years ago. It's a cute little pullover, sized to fit 0-6mths, 6-12mths and 1-2 years, and featuring a stranded fish pattern. The stranded knitting makes it really warm and cosy to wear, and you can work it up in lots of different colour schemes. The pullover features a buttoned back opening, so there's no difficulty in dressing a small wriggly baby!
Here's an example of an alternative colour scheme, with a matching hat - the pattern for this isn't available, but I just used a basic baby hat pattern and added the stranded fish motif and a pompom!
I'm in the process of completing my own Christmas gift knitting, so I'd love to hear recommendations for other patterns that would make great gifts. Happy knitting!
