I had my bridal shower last Saturday. I haven't had the chance to go out and get thank you cards. Am I suppose to send out thank you cards to everyone who came? Or just the ones that bought me something? Can I wait until after the wedding and send them out all at one time or are they separate send outs that should be sent out with in the first few weeks after the shower? I got a few gifts cards and some other gifts.. don't know proper etiquette for this and I don't want to be rude to the guests who showed up and/or bought me something!
