well maybe not THE world but at least your living room carpet.
I was at CostPlus World Market recently and was impressed with their nice selection or small cotton rugs.
Most homes we visit have synthetic rugs/ doormats in their kitchen and entry areas. While cheap to buy, their absorbency and ability to grab oily soils from your family’s shoes can’t compare to 100% cotton. Their two sided rugs can be used on both side before washing in the gentle cycle in your washing machine. Drip drying is suggested.
