Tuck one into a drawer or storage chest. Loop one over a clothes hanger. Add one to a vacuum cleaner bag. These Scented Sachets have so many uses. Crisp blues and a clean, natural fragrance—like freshly washed linens on a country clothesline—make Indigo Cotton irresistible. Indigo cotton combines the freshness of linen with powdery floral undertones of violet, carnation and lily of the valley.
