DIY Light Canvas
Such a simple idea. Punch holes in a blank box canvas and push your set of fairy lights through. Secure the end with tape. I hung ours on a storage dresser but you can use battery operated lights if you are hanging it on a wall and you don't want to see wires.
I chose a simple tree shape and the boys were ecstatic when they came down from their bath to the big switch on in the play room!
