Wallpaper is seeing a resurgence in popularity after a long period of disuse. A growing number of small indie producers is bringing a new style of wall paper that is perfect for accent walls. The above design is from Aimee Wilder and is a great touch for a light and bright room.
Many of these new producers focus on well designed prints with an emphasis on sustainability or small scale production by hand. This yellow burst design is from Makelike.
The Aquatic print is available from Pottok.
The Peacock print from Madison and Grow is available in a couple of standard colors, and even in custom colors upon request.
