Why I Love It
I love pieces that help connect what is already in a room. A pillow like this can pull together color and texture while still keeping the space comfortable and lived in.
If I Were Styling It in Your Home
I would let this be either the pattern or the texture in the grouping, rather than surrounding it with several competing statements. Layer it slightly in front of a larger solid pillow, or use it alone on a chair. Look for one color in the pillow that already appears in your rug, artwork, or drapery; that small repetition is usually enough to make it belong.
A Little Designer Advice
If your sofa already has several patterns, I would replace one rather than add another. More pillows are not always more beautiful. Give the pattern you love enough quiet around it to actually be noticed.
