This cardigan is made out of granny squares. So im labeling this as a one size at the moment. You can measure out how many granny squares you need to make your size out of my measurments.
If you’re making a different size than me use a piece of clothing you like and add the squares over the clothing as measurement

Im a size M, this is my measurments:

1 granny square is 6 x 6 cm. The back is 47 cm long including the ribbing and 55 cm wide in the back. 38 cm long arms with the ribbing. Hopefully this helps when making your size!

These are not precise weights of the yarns but a ball pin of how much I used.
200 gr yarn of yellow
600 m yarn of white
1000 m yarn of blue
