1. Prune the branch with the pruning shears. It has to have a flat bottom so that it can stand as a small tree.
2. Glue the little tree onto the middle of a sheet of cardboard, approximately 25 x 25 cm. To support the tree, glue short, narrow pieces of cardboard around the foot. Both the tree and the pieces of cardboard need to be glued down well.
3. Study your little tree closely and decide where in the tree you want to build your house. Consider whether the house consists of several small buildings and what views you would like to have for the individual rooms.
4. Choose the scale you want to use, 1:20 or 1:50. Place your scale figure in the house model from time to time so that you maintain the right scale while building.
5. It is a good idea to place the floor on the bifurcated branch. Cut out a piece of card as a floor and trim it to fit the branch.
6. Also think about how you will come up into the tree and how you will move around in it. Ladder and stairs can be built using thin sticks or wire, for example.
7. Continue to build walls and a roof for your house out of card. Remember to cut openings for windows and a door before you glue the walls in place.
8. Use artificial or modelling grass if you want to have small gardens or green spaces on your model
9. Finish by placing your scale figure in the model.
