This concept transforms the traditional Christmas card into a memorable keepsake by combining greeting and gift in one. The “Deer Card” is crafted from vegetable-tanned leather and designed using folding techniques, allowing the stiff material to behave like foldable paper.With just a few folds and a small belt lock, the card converts into a freestanding leather reindeer sculpture, ready for display. This dual functionality—as a greeting card and a DIY decoration—creates a playful and lasting experience for the recipient, making the holiday message more engaging and memorable.
