Cut long strips of cardboard to make surrounding walls.
Create the classic castle design by cutting square shapes along the top to form battlements.
Children can draw stone blocks using gray markers or paint.
Step 4: Build the Main Gate
Every castle needs a strong entrance.
Create a large gate using cardboard and decorate it with:
