Lisette and All, Have asked the other half if she has seen these drapes you are looking for in any of the catalogs she gets in the mail. Has informed me that she has seen them in Dr. Leonards catalog, one set being foam backed. Cannot vouce for how well they give total darkness. http://www.drleonards.com/Home-Furnishings/Windows-Walls/104600/999/2/products_page.cfm The other catalog is from the Vermont Country store. They offer four seasons blackout curtains http://www.drleonards.com/Home-Furnishings/Windows-Walls/104600/999/2/products_page.cfm Hope this helps in locating the drapes you are looking for. If all else fails, black plastic attached with velcro strips around edge of curtains might provide the darkness you seek. Gerald in IL [Posted in FML 5400]
