I reuse the kids pictures including the ones of a large roll of paper they have on a drawing board. Also I save the brown paper that comes in a lot of deliveries as packaging. It's great because it's perforated so you can tear it to the right size. I'm going to get the kids to Decorate it for Christmas paper. I do always think I must look like a right weirdo though when there are loads of immaculately wrapped presses at a kids party and then ours in some random reused bit of paper! One year I saved all the full page pictures that were in the centre pages of the guardian (which was delivered to work everyday) for a few weeks before Christmas and these looked really good as wrapping paper.
