First preheat the oven to 275 degrees. On a piece of parchment, use a rolling pin to make the clay 1/8 inches thick. Then cut into strips (not necessarily accurate) of 1/2 inches wide by 4.5 inches long.

Cut a sharp corner at one end (one end will get stuck in the soil) and the other end will be flat. Starting with the first letter, immerse the letter seal in a small amount of water, and then suck up the excess. Dip the seal in gold powder and then print it on clay. Shake gently in all directions to get a uniform text effect. The rest of the letters continue to do so. Put the plant label on parchment and bake in the oven for 7 minutes. Take it out of the oven and cool it completely before use.
