The sweetest little cow for a small child. You can put a rattle in it, if you like.
The heigt is about 11 cm (excl ears), but you can choose to crochet in thicker yarn, which will make it bigger

You must have a some experience in amigurumi, as there at small details in the pattern, that can be difficult.

I also make the duck for music box for small children. Read about that in my profile.
