Under Three Inches Tall
A height of 7.5 centimeters, a width of 4.5 and a closed thickness of 0.5 keep this within the space of an envelope or a wallet pocket. Nothing needs assembling: it opens and holds its own shape on a nightstand, a desk or a shelf. The scale is deliberate, since a full-size sign in a bedroom reads as decoration while a small one reads as a note.
Folded By Hand
Each one is built by hand, and the paper keeps it light. The layers stand off the base so the lettering catches light from the side, which is what makes it look like a miniature of a real sign rather than a greeting card. Paper also means it travels flat inside a card envelope and opens again at the other end without damage.
Left To Be Found
The usual way to give this one is not to give it at all. It fits in a bag, a lunch container, a laptop sleeve or a suitcase pocket, and it turns up hours later far from whoever left it there. Couples living apart can mail it inside a card. Once discovered, it tends to end up standing on a desk for a while.
Anniversaries And Galentines
February is the obvious month, but a small sign works for an anniversary dinner, a birthday breakfast or a friend having a rough week. It sits among a spread of anniversary decorations without crowding the centerpiece, and it stacks into a gift box with other small things. Nothing in the wording ties it to one date or one kind of relationship.
