Sometimes small change can make a big diggerence in updating a room. I was hired to do a rare exterior faux finish job--painting new shutters to make them look old and weathered, and the lady of the house wanted to make a few minor changes inside. One thing she wanted to change was to recover her pillows on her existing off-white slipcovered sofa. She had already bought the fabric and just needed the covers made.
I thought the fabric looked great in the room, but I didn't think two pillows recovered would make much impact and thought that doing 4 pillows would look too cluttered. A more modern idea: one giant pillow. I just used a body pillow from Target as the form. It might not be the most practical solution for a heavily used sofa, but this is a little used formal living room. Plus you can still sit comfortably in the corners without moving the pillow. I think the large surface lets the pattern shine and the one long form gives a more modern feeling.
