The Meraki jumper is a size inclusive and made to measure pattern, this means you measure yourself and then follow the instructions.
The pattern is an advanced beginner level that uses US terminology.
You will need any type of 8ply (DK weight) cotton yarn and a 5mm crochet hook. I used roughly 1100m of yarn for the sample size (UK 8), which was roughly 350m for the red and 750m for the cream.
