The Great Wall of China is one of the wonders of the ancient world, built by many different people at different times. The finished wall, which was built not only along flatlands but also through rugged mountains, is more than 4,000 miles long. While your craft won't be quite that long, you can still replicate the Great Wall in a variety of ways.
Replicate a section of the Great Wall of China using paper and glue. While it is certainly possible to design your own paper model to fold and glue, a template is a good idea. Creative Corner's template links two towers with a walking section through rugged mountains and rocks. The design is three-dimensional in grey, white and green.
Use a combination of air-dry clay, paper, and three thin, empty tissue boxes. Colour the paper to resemble rocks and hewn bricks, and glue these to the wide sides of the boxes. Colour more paper to resemble the walking path and glue to the skinny side of the upturned box. Join each box with the box next to it by building a tower using brown or grey clay. Remember the tower is a lookout post and has a wide, flat space for soldiers to pace with a 360 degree view of the surrounding area. The lookout is fenced like a balcony to discourage intruders. Adorn the path and tower with plants made of paper or clay. Join the walkways and lookout with craft glue or double-sided tape.
Build a foundation for the découpage out of small boxes. Small shoe boxes will provide a good foundation for the wall and lookout. Lay them on their sides and join by a small shoebox standing upright so that it is taller than the other boxes. Wood also works well, as the paper will adhere nicely to it with this technique. Using grey and brown paper, découpage the sides of the boxes. Use white or light grey to do the walkway on top of the wall and the wide balcony of the lookout tower. Découpage is the right texture for the wall and should render satisfying results. Once the sides have dried, use the same technique to add green brush and small trees or large rocks for authenticity.
