I always love boxed invites. thats what we ended up getting. from this company

They are beautiful, and if you are crafty you could probably do them yourself. They sell boxes that look like this at my local Rag Shop. Print out nice invites and RSVPs etc and put them in colors that match your wedding. Its always important for your invitation to look nice, remember it is the first sight that people have of your wedding.
