I think throw pillows can change the whole look of a room. I think I have changed the throw pillows in my living room at least (and this is not an exaggeration) a dozen times. They have been green and yellow, neutral, french country, cow print, pastel chevron and now are a mix and I know I am missing a few in there...I pretty much lost count.
I love how changing a few pillows can change your color scheme, add textures and adds prints to a room. It is, in my opinion, next to paint the cheapest way to transform a room. And not to mention a lot less physically demanding!
The best grouping of pillows to me is when they don't quite go together. Mix the patterns (stripes and plaid and floral), mix in an array of one color (all shades of green), mix different sizes (big, small, lumbar, round) and so forth.
Here are some great examples of what I think a good mix of pillows is...
All in the same color scheme with some symmetry but a mix of patterns and sizes.
Love the round leopard pillow thrown in.
Great mix of color, shapes and textures.
All have same color scheme, but fun patterns to incorporate it in.
Here are the pillows that are residing at my house...for the moment!
