Using these Casey cotton flat sheets is a breeze. Just put them on your double bed like you would with any regular sheets. For a more comfortable sleep, smooth out any wrinkles before you lie down. When it comes to cleaning, you can machine - wash them in cold or warm water with a mild detergent. Avoid using bleach as it may damage the fabric. Tumble dry on low heat, and take them out of the dryer while they're still slightly damp to reduce wrinkles. After drying, you can iron them on a low - heat setting if needed. With proper care, these sheets will maintain their softness and durability for a long time.
