The ever-popular Kansas City-based Ampersand Studio has applied their bright, whimsical designs to peel-and-stick wallpaper in collaboration with Chasing Paper. Both designs are floral prints. Floral Cut Out is available in a bright, cheerful yellow, bold blue, gray, and a pretty, lively multicolor with blues, greens, yellows, and pink.
Fine Point Floral features charming line drawn floras against white, or rich background colors of blush and blue. Peel-and-stick samples are available as well, and the site has a handy footage calculator.
