When FH and I got engaged, there were a few people who sent cards. One sent money. One sent a picture frame. My cousin just got engaged and I realized.... I have no idea what the etiquette is. We already picked up one of those cute Papayrus cards, but do we send anything with it? They're in NY and we're in AZ. We're not crazy close, but they are invited to our wedding. I've found so many different suggestions on Google so now I'm just at a loss. So what should I do?
