Oh my god. It's... it's AMIGU-MOOOOOO-MI. (Yes it's Casper writing this).
These cows are udderly adorable and I will hear no differing opinions. There's three different sizes of cows and one of them even gets a HAT. I think they all deserve fabulous outfit choices so feel free to experiment. With amigurumi it really is just a matter of making sure your increases and decreases are in the right place. You've got this. I believe in you. And, when you get compliments on your beautifully crocheted cows, milk that for all it's worth.
I don't apologise for the puns.
