Unique Invitations

Hi,

My heavenly 17th bday is coming up. Obvious my theme is heaven. Angels clouds the entire enchilada. My colors are blue white and gold.
For my invitations i wanted scrolls. But the scrolls i wanted... Way out of my budget. I couldn`t find any that suited my budget as well as my tastes.

I really did not want to result to just an invitation card and envelope. But I have no other ideas for unique invitations. Any ideas anyone?
