Using these Casey cotton sheet sets is a breeze. Just put the fitted sheet on your split queen bed (60cm) with the help of the tags to ensure proper placement. Then, lay the flat sheet on top and add your favorite pillowcases. For maintenance, simply toss them in the washing machine on a gentle cycle with mild detergent. This will keep the high - quality fabric in good condition. Avoid using bleach as it can damage the cotton. Also, don't dry them on high heat; a medium - low setting is best. With these simple steps, you can enjoy the comfort and durability of these sheets for a long time.
