I don't have a registry, and everyone who is invited to my shower knows we are saving for a large home project. From the people who have talked to my mom, it's sounding like they'll be giving cash or Home Depot gift cards. Because of this, would it be rude to NOT open anything at the shower? I'd feel funny just opening cards in front of everyone. Not only is it boring but I wouldn't want any guests to feel awkward with others seeing how much they gave. There may be a few box gifts but I'd prefer to open those afterward, so those who brought cards don't feel funny. How would you handle it?
