Fabulous product!  I placed it over vinyl paper and used a universal adhesive product (for prepasted, non pasted, etc.). I also had to paper in many small and difficult spaces (long, skinny areas in corners around trim). The pattern is easy to work with and the paper is high quality.  It is very forgiving and looks beautiful when hung.  The colors are beautiful and make a nice accent in a room.  I measured the area and double checked using the calculator tool and had plenty of paper. I would definitely recommend this product!
