I made another card with the cows on the front. A lot easier to do in english and it has just gone live in my Etsy store here. On the front it says "We herd it was your Birthday!!...."
On the insert it says "........So mooo-ve on over and let's party"
I think it's a good card for a farmer, or maybe I shouldn't say that!! Perhaps I should say somebody who is fond of cows! That would be more proper I think. (I do live in a farming area).
