Using your new cotton sateen sheet set is easy. First, put the fitted sheet on the mattress. Make sure the elastic band goes all the way around to keep it in place. Then, lay the flat sheet on top and tuck it in at the bottom. Add your favorite pillowcases for a complete look. When it comes to cleaning, you can simply toss the sheets in the washing machine. They're color - bleach safe, but it's a good idea to follow the normal washing instructions to keep them in great shape. After washing, tumble dry on a low - heat setting. Avoid using harsh chemicals or fabric softeners that might damage the softness of the sheets. Keep them in a cool, dry place when not in use to maintain their quality.
