My postcards stack up next to my computer and the idea is that I change out the display on the wall every time I get enough postcards in the stack to make a new row. That hasn't really happened, I've just been stacking.
It's been months since I've switched them out. But it's time. A gust of wind made the currently displayed postcards askew.
Here's the new result. 44 postcards displayed.
They look great.
