This may sound silly, and someone may have already asked this and I didn't find it, but is there a general about how many items you should register for? I would guess it probably has something to do with the number of guests you are having but I have no idea. Say you are inviting 100 guests. Would you try to average 80ish items on the registry? I am afraid of looking like we are asking for too many things, but also about not having enough for people to choose from. What did all of you ladies do when registering?
