I'd like to draw a tree on our hall wall so that I can 'hang' family photos on the branches. (I've looked at tree decals and the ones I like are really expensive).
If I come up with a design on a piece of paper, is there a simple way of projecting it onto a wall to guide me? (I haven't got a projector so this is going to sound really dim, but I'm possibly overlooking another way of doing it using something I already have).
