Print words on basic white paper in mirror image form, lay them on wood. With a damp paint brush wet the paper on top of the words. Use the cap of a sharpie to rub on top of the letters to help them transfer, then remove the paper.
Print pictures on old book pages. Looks amazing. You could use a book that has special meaning with the picture or maybe sheet music. Perhaps you would like your wedding picture placed on your favorite song from your wedding. Would make a great gift too.
