My son started his freshman year of college last week. I mailed him a couple things he meant to take and included a bundle of handmade postcards.
I wanted to gently suggest that taking pen in hand and writing a little letter is an awesome thing to do, both for him and the recipient.
To make them, I took some background layers that never went anywhere and cut them into postcard size- rectangles.
On the other side, I drew line roughly down the middle and made a stamp-shape in the upper right corner.
I added a sheet of postcard stamps and sent it out.
