Awesome idea for used wine bottles.Use bottles, soda bottles, beer bottles, or wine bottles. Cover a part of a bottle in red paper. Spray paint everything else white and cover the red with stripes of white, and turn it into letters.
Christmas wrapping idea: Buy brown wrapping paper (cheap to buy at Walmart or a craft store) and use that paper to wrap your gifts. It's useful for every gift, and you can customize it by writing on the paper.
