No more toilet paper tubes

Have you heard?  Kimberly-Clark has announced that they will be removing toilet paper tubes from their toilet paper.  Technically, apparently they are called cores, but you know what I am talking about: the cardboard center of the toilet paper roll.

Apparently, toilet paper tubes, according to Kimberly-Clark's October 28th press release, toilet paper cores account for 160 million pounds of waste.  Of course my question is not why we are taking it out, but why didn't someone think of this earlier? And does this mean we are going to have less expensive toilet paper since this part is being removed?  And of course most importantly, how are we going to do all those Kindergarten crafts?

My next question is, when will someone be innovative enough to do the same thing with paper towel rolls?
