For the first one, I used the numbers of the date 4. 21. 12 to create a pattern and turned that into a frame. I really love how the numbers reflect each other so I went nuts.
The second and third ones make me think it could be an esteemed whiskey label. We might save that for the actual invitations and not the Save-the-Dates, as it would look like the most serious and slightly threatening game of Scrabble.
Since Jenna wanted her engagement photo AND Scrabble, all I could think of was "scrapbook." This needs work, obviously.
