I had a Christmas card sent to me in an obviously recycled brown envelope with a sticker over the previous address. Then the card itself was a bigger surprise. The card had been sent to him previously, he'd crossed the names out and replaced with mine and him as the sender. Not even used tippex! He's not short of money. He's also done the same with other friends.
It's made me think about recycling mine but I'd buy card blanks and mount the pictures from the original cards, not do this which might be well intentioned but makes him look a bit batty and scroogey.
