No sewing needed for the cloth version, either, if you back the 8-inch swatch with a square of fusible non-woven, stiff interfacing. Just iron-on, cool, and cut out the tags. Then use a pointed yarn needle to sew a piece of yarn through one corner for attaching to your gift. Or hole-punch, and thread with yarn or ribbon.
A repeat that fits the full design on the 15-inch and 30-inch decals can be seen here.
