Venetian blinds have been around for more than 200 years, but the exact source or country of their origin is unknown. The slats come in various styles such as 1-inch or 2-inch widths, which can enhance the look of the blinds or let more light in. These blinds also come in aluminum or vinyl materials, depending on your preference, and can be relatively inexpensive. Venetian blinds do require routine maintenance to keep them free of dust. You first need to remove the blinds before you can clean them or to transfer them to another window.
