This cute little baby cow can be made in most types of yarn. The heavier yarn you use, the bigger a cow you get. The one in the pictures is made with yarn similar in weight to sock yarn.

You will need 3 colours, white, brown and pink.

I used less than a 50 g skein of each colour (much less than that of the pink)

The pattern has guiding pictures for specific things like the hoofs and the ears.
