Its funny to think of all the time spent in History class in high school , or actually all the times that I cut that class,learning about geography and of course maps! I thought I would never be interested again!
But in designing a children’s bedroom right now, for two young boys, they are going to share the bedroom, I am thinking that a wall or the walls, all being in maps, wall paper of ocurse, would be so interesting! There are some really modern interpretations that I found by google. 
I am also considering on one of the walls, as it is a large bedroom, this fabulous blackboard paint for them to go crazy! So lots of inspiring thoughts in their room!
There are some wonderful companies now that have map wallpaper like Pierre Frey, and Ralph Lauren, Thibaut and a few others!
