Most of the time I use a gift tag – or no tag at all – when I give a present, but every so often a card is necessary. Either because the occasion calls for it (like a wedding) or maybe I just have more to say. But when the gift is smaller than the card, it can be hard to keep the pair from getting separated.
That's when a cellophane bag can come in handy. Put both the card and the present inside, and tie with a ribbon. The card and gift stay together, and you can still see the pretty wrapping.
