This is my own pattern that fits 12″ Blythe dolls.
This is a Monster of a sweater with extra looooooong arms, a roll neck and a little moss stitch hemline.
I use this pattern for all my Monster parade sweaters which I have made from lots of different types of yarn. It’s fun to experiment!

You will need 2.75mm needles and DK yarn (UK) other fancy yarns work well, it will just come out bigger but that is part of a monster’s charm! To make the face you will need a scrap of vinyl, two 4 hole buttons and some cotton crochet /embroidery thread.
