This is a winter pattern because of the thickness of the reversible cable. I’ve used two types of yarn (held together)
The first is a chunky one (generally knitted with needles 7mm)
the second one is knitted with needles 4mm. (US 6)

For this project, I’ve used needles 12mm. (US 16)

The pattern is available in French and in English!
This is the first version of the pattern, feel free to contact me if there are mistakes.
