If you’ve got a plain Jane sofa and you want it to look more formal a surefire way to do it is to add some nailhead trim. Simply determine the lines of the sofa you want to accent and then nail in the tacks (try to place them at even intervals of roughly ½ inch). Just be sure to choose a solid part of the frame so you’ve got a solid foundation to nail the trim into. And it should go without saying that you cannot do this on a slipcovered piece – only on one that’s upholstered.
Wrap the foam with multiple layers of batting. A small amount of spray adhesive applied to the foam can help the batting stick to it so it stays in place once you put the covers back on. If possible, have someone help you put the covers back on the cushions. All those layers of batting make it a tight fit- but that is what you're looking for, so ask someone to lend a hand to make your job less painful.
This is what it looked like when I arrived. As you can see, it actually had frown lines and wrinkles. What kind of witchy sorcery did I use to create this magical transformation, you ask? A super top-secret, rare fiber found only in every craft store ever. I used Poly-fil, an easy-to-find, cheap (a 10lb box will run you about $30) blend of polyester that has a high tolerance for wear and tear.
