Monochrome Beanie basically named by its yarn color.
This pattern is unisex, with a lot of color option of your choosing.

Additional: here’s a video I made to explain the brioche part.

The size option only available for 40 cm (16”) circumference, but to make another size is possible from adding or subtracting multiple of 10 sts.

Number of skeins I needed for this beanie around 50 gr of each color.

The pattern has been tested.
Notes:
But the 20 cm (16”) circumference is not stretchy, so it wouldn’t fit for adult. If you would like to made it for adult size, add multiple of 10 sts.

Thank you
