Here is a Christmas card which I made for my cousin and her husband. I make them one every year with a cow on! The rubber stamp is one that I have had for years - I think it came from Blade Rubber.
Card blank, and the black and white card are from Craftwork Cards as is the In-Circle message. I used a Copic marker to colour the cow's udder. The card was simple to make but it looks very effective.
