These little notebooks are pocket sized composition books that I altered. I LOVE these little books and have altered some for each of my kids now - I asked Laurence if he had used his and he says he uses it a lot as a little diary! :)
You can get a pack of 4 for $1 at the dollar store on Wye by Safeway.
I also love altering the bigger composition books. You can get them at Staples for $4 each but to be honest I prefer the ones from Dollarama at $1 each! They seem to be stronger and the pages don't fall out!!! :)
