GifToppers are full-sized greeting cards designed to be hung on a bottle of wine. The advantage is that the card doesn't have to be taped to the gift as with traditional greeting cards, or presented separately.

The company that makes them, David Gregory, Inc., hand makes all GifToppers from their store in Fairway, Kansas. You order them online from the company, and can have them print your name or business logo. They have several designs and occasions to choose from.

Of course, GifToppers can be also be hung on flowers, gift-basket handles, or the antenna of a brand new car you just bought for your wife.

Seems like this is the kind of thing crafters can go crazy with.
