Because every piece is done by hand they require anyone who works on the paper or fabric to have a background in fine arts.
Some of my favorites. When you are looking at the colorway swatches it is best to invision them more like and entire wall vs how you normally look at a wallpaper sample.
There is always the option to frame some panels instead of doing you're entire wall!
Or use the print in fabric!
