a pattern calling for Malabrigo Chunky. Following the "but it's just a hat" rule of thumb I didn't swatch. And what you see before you is a hat that with any luck will fit a toddler. Bottom line, the yarn is not chunky enough, I am inherently challenged with stranded knitting being too tight, so we'll just consider this hat my first swatch. As far as the size goes, there's nowhere to go but up!
ETA: I forgot to say though, that sometimes things go right! :-)
Amanda is right--it's a lot easier to make something fit well with top down construction that you can try on as you go.
This is Knitting Pure and Simple pattern #267 Neckdown Bulky Bolero knit in Noro Iro.
