One of the more difficult cards to make is Condolence cards. I found this kit made by Anna Griffen for just such occasions. I think the card looks clean and simple and yet elegant for the needed occasion. I don't have a current occasion for such a card, thankfully, but when such an occasion occurs, I don't exactly feel like making a card. I go to an elderly church, we lose about 10 members a year..
Hope you are having a great day!
