Using these Casey Cotton Fitted Sheets is a piece of cake. Just place the sheet on your queen - sized bed with the 60cm depth and use the tags to make sure it's in the right position. When it comes to washing, you can toss them in the washing machine on a gentle cycle with mild detergent. Avoid using bleach as it may damage the fabric. After washing, tumble dry on a low setting. To keep them looking and feeling great, iron on a low heat if needed. These sheets are durable, but try not to over - stretch them when putting them on or taking them off the bed. With proper care, they'll serve you well for a long time.
