These post box hats are popping up everywhere. They definitely spread some happiness and cheer. I spotted this one yesterday with it's pink flamingos and pom-poms so just had to take a photo for today.
Nice idea! We don't seem to have any stand along post boxes in our neck of the woods. Ours all seem to be small, and incorporated into walls. The idea wouldn't work quite as well here, unfortunately. This is lovely.
