Bermondsey beanie is knitted in the round using a 4ply wool.
The main hat has a simple 2 col fair-isle but the secret is a contrast colour facing, which can be worn down with just a hint of colour showing - or turned up.

The pattern comes in 2 sizes - womens’ small/medium or medium/large.

I’ve included exact amounts of yarn in the pattern - so it could be knitted using odd bits of wool!
MC - 25 - 30g; CC - 15 - 20g; facing - 17-22g

I’ve also designed long arm-warmers of short hand-warmers using the same yarn and fair-isle. See separate pattern.
