Oh what? I'm using my own wedding invitations as a portfolio piece? Yeah, I am. Because not only am I a super-picky client, but I also printed these using light-sensitive ink, which was kind of a major project. 
First, I designed the invitation in Photoshop. Then, I created a transparent version of the design to use on printmaking paper that I'd treated with light-sensitive ink.
Then, I let each sheet expose for 12 minutes, then washed it and dried it.
The finished product, with stamped envelope:

Sunprint Invitations

I created my wedding invitations by designing a transparency and using the sun as my printer. This is how they turned out.
