Made this treasure map for my son sometime last year. There was no actual treasure, nor any hunting. He just wanted a map.
We found it today and after a short talk about it I thought it would be worth sharing. I drew it using only a broad calligraphy pen, and it was a fun exersize. Choosing a limited "tool-bar" helps to create a uniform and coherent look, and the specialised pen worked alright in this sense. Just like choosing a limited pallette of colours for a miniature I guess.
