I collected toilet paper rolls for weeks, hoping to use them for some sort of to-be-determined craft project. Neela thought I was crazy and threatened to throw my stash out in my sleep if I didn't do something with them. Finally I came up with the idea of cutting cross sections and making a map of India on our living room wall out of them. Bangladesh (what what) is prominently displayed using bright orange origami paper. Take a look at the pic from this post to see where it is in relation to the rest of the room (its in the left corner).

BTW, can you tell yet that I use origami paper for everything?
