I like so many colors, fabrics, textures and designs it’s hard for me to zero in on any one thing. If you have a piece of art you love, take a look at the colors and pull from that for your inspiration.
Layering pillows adds interest and warmth to a bed or sofa. Start with the largest pillows in the back working to the front of your arrangement using progressively smaller ones.
Usually a good rule of thumb is a few larger sized pillows is better than dozens of little ones.
