This sweater in the Nordic star pattern was made for my granddaughter. She would have preferred pink colour though….the yarn is very soft and warm and yet not heavy. You can use any yarn - the pattern is very fexible.
It is knit top down so you have the possibility to regulate the size.
If you use thinner yarn and needles it might fit a smaller child.

The name - comes from a crimi-serial - and the woman detective wears a similar - very popular - sweater.
Just ask.
