knits for adults
3-in-1 by alfa design
And here are a few really warm ones, made with super chunky yarn. The green one is a simple cowl, the red one is wrapped twice and therefore even heavier.
To complement the look with something small and simple I have recently discovered knitted hairbands. They are great for longer or shorter hair and add a bit of colour.
From the hairbands it is only one step to headbands in winter and maybe a second step to a proper hat.
