The first couple of summers my fiancé & I were dating, we happened to be apart. To make the distance shorter, we sent each other cards every week.
We would each decorate the outside of the envelopes with meaningful or funny symbols of our relationship.
To find different ideas took a lot of thought, but it let the other person know we were thinking of them. A couple of ideas we tried were:
a) make the envelope into a „pop-up” book like when you were a kid with pull-out thoughts and more
b) draw a picture of you and your love doing something fun together
