buy a projector, place projector with image you want and have it project said image on the wall......paint where the image is on the wall. Not that hard.
exactly
No you don\'t.
err, yes I do, the method phil explained is how it\'s done, it\'s not a modern concept either, the reason how I know how to do it, is because we did a similar thing about 15 years ago when I was at college to the students room.
you get an overhead projector, paint the design you want onto a sheet of acetate, put it on the projector and just follow the pattern on the wall
