Only because MissOwl requested it :-)
Here is the stamp I ordered off of etsy seller NoteTrunk. It was $30 for the self-inking stamp. They had a V-day sale, so I got it a few bucks cheaper than normal.

And, my invitations, front and back. The front has a little dotted line border, but it's not on the real invitation (these were taken as snippets off the computer since I haven't received them yet):


And, the RSVP card:

We got the invitations from Vistaprint. We ordered 200 for under $150!!!! I mean, seriously, that's nuts. We didn't get the corresponding, matching envelopes. It would have added probably about $100 more (which is why I bought the super awesome rubber stamp!) I used a 35% off coupon that I received an email about.
