Cotton
A bed-sheet is a square piece of fabric that is consists of an elastic band lining that fits directly over the mattress. Another type of bed-sheet includes stitched ends without a stretchy band. You can use both the fitted bed sheet and the straight and stitched type at the same time during hot nights.

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.
