Why bother with painting and wallpaper?
Wallpaper sticker was an option but the design they chose was not available in mall and even online.
The other option was canvass media, the medium where painters and artists use. But that medium would put additional expenses in framing the wood. Canvass is also an option given its like an old painting effect.
Given the client has limited budget only, their only last minute option which is affordable and easy to install is wall decals :). Our large format printing services can also adjust its color to your needs, since client wanted as it is then no further changes were given.
