I adore sending (and receiving!) real mail: thank you cards, holiday cards, postcards. Real, handwritten notes are part of my love language. We traditionally send cute photocards to our family for Valentine's Day, and I look forward to putting them together every year.
There are tons of great places (Snapfish, Shutterfly) with predesigned cards so you can just drag and drop your photos and be done. I've used those companies frequently in the past. This year I decided to try a different route: designing my own cards using PicMonkey.*
The best part about this is that these print out as regular 4x6 photos (or a 5x7, if you prefer) instead of a much more expensive photocard. I sent them off to our local one-hour place and had a bunch of them printed for about 10 cents each. That's an absolute steal!
Simple, beautiful projects like this are my absolute favorite!
*I am in no way connected to any of these companies, I'm just sharing because I've used them successfully in the past.
