Festive stationery in Outlook

One of my coworkers decided it’s time for an office potluck. So naturally, I have to send the announcement. How do I put a festive border into the email?

I decided to just put an image at the top of the email, so I don’t really need an answer now.

But if anyone would like to post how to do the border thing, it might be good for future reference.

“Johnny L.A.? Who is that?”

“You know, the guy who sent the email with the festive border!”

“Ohhhh, him, sure.”

I would just add a background texture:

Options > Page Color > Fill Effects - Bouquet is a cheerful one.
