A 21st birthday banner has one job, which is to make the room look like the occasion was planned rather than remembered at six o'clock. This one takes the cocktail garland route instead of the usual block letters, so it says twenty first without spelling it out across the wall. That makes it easier to live with: it hangs over a bar cart, a mirror, a mantel, or the drinks table, and it still looks right in the photos everyone posts at midnight. It also plays well with whatever 21st birthday decorations are already in the cart, since a birthday garland layers under balloons rather than competing with them.
How do you hang a birthday banner on a wall? Birthday banners typically arrive pre-strung on cord or string and hang from removable adhesive hooks, push pins, or washi tape placed at each end. Because the string is adjustable, the same banner can be draped across a wall, a mantel, a mirror, or the front of a dessert table.
