Here are some rough sketches of cover designs and illustrations. At this point it is really open ended and I'm hoping for some constructive criticism. I made four designs (some swirly, some a little more concrete) and can take any and run with them or I can scrap them and start anew.
Here are all four of them together for comparison's sake.

And lastly here is a mock up of how I was imagining the invitation, envelope and business card. We can go a bit more formal than this if you'd like. The front of the card would have an illustration/design (i.e., like those above), and the inside would have the invitation words on it. The RSVP would be one-sided (i.e., no back design, just RSVP info) and simple.
And lastly here are some fonts to be thinking about for the inside of the card. Please pick two fonts of these seven. We'll discuss fonts more in depth later but I wanted to get a feel as of right now.
I hope this is a good jumping off point and I'm looking forward to hearing what your thoughts are on these. :0)
