Group in twos with different patterns and textures mixed. On one side, add a third in the yellow color smaller size.

Duplicate post.

I was also going to suggest to pair them in twos with the largest pillows against the sofa. Mix up the patterns and colors to something pleasing for you.

You have a good mix of patterns and colors going, but you may want to pare back on the number of pillows, and mix in a couple of lumbar shapes in 12" x 24" size. Make sure all your pillows are feather filled, not poly, so that they can be scrunched and placed organically.

Frankly, I think throw pillows should have some relation to one another. Either in color (picking up a color in rug, art, etc.), style (modern, tradition, etc) or formality (casual or formal). Your choices seem haphazard and I don't see any color in the room that they are relating to.

Hi mountie,

This room is not yet yet painted and it still needs furniture pieces (coffee table, end tables etc). I have just started with sofas. I know I want blue, turquoise and yellow in the room and may be some teracotta color.

Thanks carolyngarland. I did not think of cream background in pillows. That is a good observation. I knew something was off when I saw the arrangement but could not point out what to change. With all the comments here, I have a better idea now. Thanks all. I am contemplating changing the color palette in the room. Get rid of all the pillows in my above picture and keep only solid turquoise ones which I can use elsewhere in the house. Yellow gray may be. Attached pillows for the new scheme.
