Cover the kitchen soffit with tile to give the feature texture and style. Use tiles that match your kitchen back-splash for a continuity of appearance, or use them to create a detailed mosaic pattern or picture on the soffit. Apply a layer of mortar, and press the tiles carefully in place.
Hang artwork on the kitchen soffit to hide it from view. Line it with decorative plates, hang a row of small, framed pictures along it or display long, narrow accessories across it, such as antique golf clubs or skis.
Create a short curtain that spans the length of the soffit. Measure its length and height. Add several inches to the length for a curtainlike effect, or keep it the same length for a straight piece of fabric. Install one eye-hook on each side of the top of the soffit, and string a wire between them. Use curtain clips to hold the fabric in place.
Install tall crown molding on the soffit that stretches to the ceiling. Choose wood and finish types that match your cabinets, which will make the area appear as a natural extension of the cabinets.
