Using these Casey cotton sheet sets is a piece of cake. First, spread the flat sheet over your mattress, then put the fitted sheet on, making sure to match the tags to the right corners of the bed. Tuck in the edges neatly. For pillowcases, simply slide your pillows in. When it comes to washing, use a gentle cycle with mild detergent in warm water. Avoid using bleach as it can damage the fabric. You can tumble dry on a low - heat setting. After drying, give the sheets a good shake to get rid of any wrinkles. If you want, you can iron them on a medium - heat setting to make them extra smooth. Store the sheets in a cool, dry place when not in use to keep them in great condition.
