The steps are as follows:

1. Prepare a blank piece of kraft paper, wide adhesive tape, scissors, bamboo stick and fountain pen.

2. Cut the kraft paper into the pattern you like.

3. Stick the cut kraft paper below half of the wide tape.

4. Fold the upper part of the adhesive tape downward, and be careful to flatten it outward from the crease to avoid bubbles.

5, cut along the kraft paper, pay attention to the edge to leave 5 mm wide tape and cut a long tape slightly narrower than the paper, stick it on the other side of the kraft paper and stick a toothpick, roll it up.

6. Write down the name of the plant, which family it belongs to, its distribution and use, etc. Use a pen on the sign.
