Here's an affordable, easy idea, from the Flower Council of Holland, to decorate for any celebration at the office. These pretty arrangements are based on the simple, eco-friendly idea of recycling disposable coffee or beverage cups.

Whether you're celebrating a birthday, engagement, or shower, set out several small flower arrangements along the center of the conference room or break-room table.

Or place an arrangement on the desk of a co-worker to acknowledge her birthday or other special day. Simply choose cups from the office's coffee area or local coffee shop, and purchase flowers from a nearby grocery store or produce mart.

And there it is: Instant office party décor! Or just an inexpensive way to let a co-worker know you're thinking of her (or his) reason to celebrate-whatever it is-and simply want to acknowledge it.
