As for new decor, my search for art calendars on Amazon led me to a 2010 Amnesty International Calendar for $4 with beautiful multicultural photos! I laminated many of them and they've have been a wonderful addition to Tyler's multicultural displays in his large motor room. Plus, the purchase went to a wonderful and very Montessori cause!
I also (finally) took on a huge task of laminating all of the cultural photos that I took from National Geographic so that when Ty inevitably pulls them off of the walls, it doesn't matter. This is our India display.
So we'll see how long my satisfaction lasts...I'm already thinking that a huge poster of "Starry Night" may look great in the quiet room... :)
