Need proof that pillows don't have to be formal and fussy to look amazing in your home? May I present...
Exhibit one: 
Norwegian-based blogger, Maria Aarli-Grøndalen's, home boasts a charming pillowscape with muted teal walls and books in the window sill for a quiet afternoon. See more of Maria's home on her blog Nordic by Maag blog or her profile on at{mine}.com.
Exhibit 2:
Inside Chic chose this candid little pillowscape when they interviewed me about my work and pillow designs. Here, my Geo fire bolster , leans on one of my favorites, a pinwheel cushion my mom made for me with vintage fabric. Here the artwork is center stage, the pillows a lean supporting cast.
Exhibit 3:
The key to finishing a casual inviting room is to create pillowscapes with contrasting colors and patterns, like this scene styled for a Kelly-Moore Paints video I produced and hosted last year. (click here to see this color blocking video)
Exhibit 4:
For formal or more quiet neutral spaces, focus on texture, tone, and natural fabric, like my living room, shot by Liz Daly for Anthology Magazine in January 2015.
Closing Argument...
For me, there's time a room for every style pillowscape, except those that are lined up like soldiers with karate chops that make you feel like severe repercussions will ensue should you get too close. Skip those altogether and just relax into the scenery with pillows that support your body and enhance your home.
