Different fabrics and weaves have different characteristics and therefore have a different feel. The best bed linen is made with the highest quality natural materials and woven to the highest standards.
But when was the duvet invented? No one really knows.
Cotton is a plant that loves warmer weather and it takes several months for it to produce the fluffy cotton balls that we all know. After the plants are harvested, they are defoliated and send to the cotton gin. There, the cotton fibers are combed — this is done for cleaning and fiber straightening purposes — and then spun into yarn.
Cotton Sheets
Silk is a natural fiber produced by silkworms and because it needs such delicate care in the production process, it tends to be a pricier option. Aside from the price, silk sheets are naturally hypoallergenic, but care and maintenance tend to be laborious.

Flat Sheet
The flat sheet is the first covering over the fitted sheet. It's the layer that touches the body, providing a hygienic, easy to wash barrier between you and other bed coverings used for warmth and/or decoration. Luxury sheets can hang down the side of the mattress though traditionally they are tucked in all the way around for a more polished presentation.
