In our old house, when Sophie's room needed brightening up, I turned to a very simple fix. I enlarged a photo her on the computer, then printed it out and traced it on to different coloured A4 paper. I glued the dancing girls on to stretched canvas at regular intervals, giving the illusion of motion. It was a very effective, but cheap (!) way of bringing colour in to her bedroom. The original photo was of Sophie showing her grandparents how she can do Irish dancing - no lessons, just learning from daddy! I think she's a natural!
I'm hoping for a small window of time during the last week of term, so I can make a few quick and easy projects for the kids' bedrooms - any suggestions?
