I have a love/hate relationship with World Building. It's a brilliant puzzle but it's also a nightmare when your world gets too big for you to sort out all the information in your head or even through a journal. To help with this, I started drawing. I'm not great at it but the images help me wrap my mind around my story.
As I've said in other posts, the second novel in my trilogy is bigger than the first. The first one only took place in two locations. This one encompass several villages spread across the country. To get a better feel for terrain and distance, I bought a form board, pencil and markers, printed out a map of the United States and drew it onto the board. I also needed the locations of all the major cities in the US so I Googled it. Maps of World was awesome for this. I needed physical features too- mountains, bodies of water, things like that. Again, Maps of World was so helpful. Since this is a form board, I pinned strips of paper on it with typed details about this world. The map is on my wall.
