I found this quote on one of my favorite websites (
www.quotegarden.com) It's a great resource for stuff like this!!!
True love stories never have endings. ~Richard Bach
Last year I made an invitation for a going away party for a close friend of mine.
Gallery at Splitcoaststampers I just used one quarter of a page of cardstock for each invitation. I did the flowers and quote on the front and then put details about when, where, etc. on the back.
In my opinion this quote would lend itself well to doing a simple background using hearts then layering the quote on top. On the back you could start by saying something like "Please join us as we celebrate the story of (parent's names.) then list all your details. Just an idea hope it helps! And be sure to post whatever you come up with! We look forward to seeing it!
