We get married on 01st March and have not set up a gift list or asked for anything as we neither need nor want anything 9other than to get married) and I would have been perfectly happy if we didn't receive anything. However, my mum text me last night to say a couple of presents have been dropped off with her and a friend who can't make the wedding dropped a present into my work this morning. I'm over the moon of course and think it's lovely of them but what's the etiquette on this- do we open them now and send thank you cards or wait until after the wedding?
