How do I switch credit cards without taking a hit (or at least a major hit) to my credit? I hate the bank I’ve currently got a credit card through, it’s my only account with them, and I’d love to get a card through my credit union and close the old card, but I think I’ve read/heard that closing a credit card is a ding against your credit.

I recently bought a house with my wife, and we’ve otherwise got stellar credit, I just don’t want to feel chained to one card through a bank I don’t like.
