Veags theme - Custom cards printed up with the invitation on the back!
Island theme - A scroll in a bottle (even include some sand for laughs)
70s/ Diso theme - Check out spotlight for 70s material and use a marker pen on it.
Goth theme - A black envelope will stand out, try sealing it with red wax and a stamp.
That’s a few to get your creative juices flowing :)
Until next time keep rockin'
