Here's the other sweater I have knitted for Theo. I took part in a test-knit for Gabrielle Danskknit on Ravelry for a children's sweater. The pattern is called "Grown-up" and should be released any day now.
This was a really fun knit and a nice opportunity to play with color. I chose quite sombre combination of grey and pale yellow. I still prefer to dress Theo in gender-neutral colors, because he wears the clothes for such a short period and maybe if we one day get another baby it will be a girl instead, so I don't want overly boyish clothes. Or if we don't, unisex clothes are easier to gift away or sell.
I used Drops Merino Extrafine for this project. It's a really nice yarn to work with, smooth and stretchy so I think it's perfect for baby clothes. The sweater knitted up really fast (might be down to the small size - by the way I knitted the one-year old size) and the stripes kept it interesting the whole time. I think the sweater would also look really good in unicolor, I might just do that next!
