I came across this today, and thought this would be a pretty neat idea. Regardless of where you decide to hold the birthday party (and if you need ideas for where or what, you can check the teen birthday party ideas page on Idea Queen)…..why not send the invitation by email? Almost all teens are connected in some way or another, so it only makes sense the invites go out where they spend the most time.
Visit AmericanGreetings.com for a wide selection of invites, eCards, and printable cards for every occasion. You may never need to search the store for cards again! Worth checking out their free trial at least for the teen birthday party.
