Wow, nice thought ! I have a similar plan in mind too. I am planning to go for some online DIY wedding invitations that stands out from the rest. My wedding party hall in Vaughan is said to be decorated with blue and pink roses and red curtains. I am planning to get those colours highlighted since it’s more of a theme wedding that’s in my mind. Invitation needs to be a prior info to convey the theme. I am working on with some ideas.
