Hi P.,
Make you own... I have some software called "Hallmark Card Studio" and I LOVE it. I buy the blank cards at Michaels and make all of my own Invitations, Holiday Cards and Thank You letters. I even made my second sons Birth Announcements and they came out way better then the "Professional" ones that we paid a ton for the first time! I printed his picture on cardstock and then a nice message about our blessing and his stats on some frosted vellum and tied the 2 pieces together through punch holes and a bow. It really is easy and I get so many complements, it is just time consuming.
Let me know if you need help finding the software. I could probably even help if you could compensate me for my time and supplies. I can e-mail you come of my "masterpieces" :-) so you can use the ideas.
