STEP ON IT
Narrow shelves can be your best friend. Fixed on the wall, even one shelf allows you to change or rearrange your art or photos at will and thus change the feel of your room instantly. One that has a lip will keep pictures from toppling over. Avoid samesized frames as a stepped arrangement will draw the eye so your sofa enjoys pride of place. Wondering how high to fix the shelf? High enough not to hit your head when seated!
