I took the inspiration for my Valentine's this year from a little video on the U.S.P.S. Instagram page. In it, they took a big heart and folded it around a card, forming an envelope. I loved it, but when I tried to recreate it, I realized that when you cut a heart from an 8.5" X 11" piece of paper, it makes an envelope on the rather small side; so small that I didn't want to chance mailing it.
Now, I could certainly have sized-up my outer heart, but instead, I chose to get smaller. I had a bunch of heart-shaped doilies in my mail art stash and decided this was a good time to use them. The heart-shaped doily is a sweet reminder of the season, minus all the calories.
I loved the idea of the heart shape appearing when the letter was opened. To create that effect, I made some tiny little cards, 2.5" X 3" and typed a short message on them. Then I folded the doily around the card and sealed it with a vintage stamp or cut-out heart. I put glue on the "back" of the doily envelope and affixed it to a 4.25" X 5.5" flat card for mailing. The cards are cut-down from card stock and so are thick enough for me to write a longer message on the back.
