We did and it was a huge hit. We bought pre popped popcorn from a local shop that does all sorts of flavors - we had regulard/cheddar/caramel/chicago style. Then we m&m's, nuts, Reese peices, and some other candys for mix ins. bought on Amazon super cute old movie style mini popcorn buckets. We got so many compliments on it. And the whole thing cost us $300!!!
We are having a popcorn bar. The sign is going to say "POPCORN BAR...because our love is POPPIN!" lol how cute is that!! We are ordering it from Poptiquepopcorn. We already samples from there and decided which we wanted to order. We are obsessed with popcorn so it's very fitting for us to have the popcorn bar.
ETA - Orientaltrading has some mini popcorn boxes (just type in popcorn boxes) that can be ordered in almost every color. They are so cute.
