Construction
Go to your nearest Target, Wal-Mart, Kmart or other type of household goods store and pickup 1 or 2 hypo-allergenic corrugated foam mattress pads. Cut into 2 foot by 2 foot squares or whatever sizes are appropriate to cover areas of problematic reflection. (more in "setup" on appropriate placement) Get some aesthetically acceptable fabric from a local fabric store, some kind of sandstone beige cotton or other usually looks good, and cover the foam pieces with the fabric. pinning works well if you don't have patience to sew.
 
Setup
Best place for panels to improve imaging and reduce image smear is on side walls approximately midway between the speakers and the listening position.
 
Use
 
Performance
Improves imaging performance by reducing "early reflection smear" and improves midrange intelligibility by partially eliminating reflective coloration associated with many room surfaces.
 
Other
20 to 50 dollars

Joong For covering, burlap is good material - other fabrics may add reflection at mid and high frequencies. Get them cheap at Wal-Marts.
