I've heard stories about magnetic Save the Dates getting stuck to mailboxes and such. And now I'm having nightmares about that and them getting stuck to each other. If we place each in its envelope in the same direction they mostly do not stick to each other. My fear is if two are touching with the recipient address towards each other they do get stuck to each other. I'm just picturing my friend's (Philadelphia) Save the Date landing clear across the country at my fiance's aunt's house (California). Is there a solution to this or do we just mail them and cross our fingers?
