I'm having a watercolor moment lately. I'm loving the softness and blended colors watercolors have. I have yet to tackle making one myself but luckily there is this great website that creates watercolor maps.
Just enter in a location and it automatically generates a watercolor version of the mapped location. You can also choose the terrain or toner options if you desire.
Above is the Mighty Birch - I'd love to get one of these framed. You can always update your computer background too! Check it out here.
