Apologies, I have added a crochet hook size in error. This is not required for this pattern.
Yarns - 4 colours are required:
4 (5 for larger sizes) x main colour.
2 (3 for largest size) x second colour.
1 each (2 for larger sizes) x additional colours.
Colours used in the original design:
Forest (442); Arran (456); Kiwi (443) and Quartz (446)
5 x 15mm buttons are required to complete the garment.
