Are they nessacary? Do you really need them or is it just something nice for the guest to have on hand. I plan on a short and sweet ceremoney is it something needed for one like that. I know its a if you want one thing as well. I already narrowed my invites and save the dates down but am stuck on if i need to do this. I really dont want to pay for something thats going to be useful for two mintues then blown away at our outside wedding. And then just be thrown away once we are inside.
