I have a collection of vintage greeting cards (some are occasion specific and some are general) and thank you notes that belonged to my grandmother so I love to use those as seen on the bottom-left. I think the notes inside of them are more earnest and heartfelt and I like to write my own messages too. but I also have fun designing little e-cards I made the one on the top-right in 2011 (!) and I made the one on the right last week ❤️
