I especially love seeing the cards made by Polka Photos clients. All of my wedding and portrait packages include photos on disc because I believe that photos keep memories alive for years to come. I also think it's fun to use those photos on cards from save-the-dates to holiday cards.
Here's a couple of cute cards from Charlotte's photo session. Her mom couldn't decide between two photos, so she made two different cards. I think both are adorable.
Liz and Joel send out annual newsletters. I love receiving them because it's fun to read their year in review. It's also fun to see which photos they'll choose.
