We are ready to send out our invitations. The only problem is that we don't know whether we should include a card stating where we are registered. In the past, I have received some invitations with one and some without.
The short answer is yes -- it's considered rude to put your registry on the invitations because it suggests that getting a gift is just as important as inviting your guests to the wedding. Of course that's not the case. Instead, put a link to your registries (most couples have three) onto your wedding website and direct friends and family there for all the other fun details. If you're really concerned that no one will be able to find your registry, do as couples did before there were wedding websites. Have your close family and best friends spread the word to whomever asks about it.
