Using these Casey Cotton Fitted Sheets is a breeze. First, take the sheet out of the package. Check the tags on the sides to make sure you're putting it on the bed the right way. Then, simply stretch it over your queen - sized bed with a 50cm depth until it fits snugly. For the best results, wash the sheets in cold water before using them for the first time. When it comes to washing regularly, use a gentle cycle with a mild detergent. Avoid using bleach as it can damage the high - quality cotton fabric. You can tumble dry them on a low - heat setting. To keep them looking and feeling great, iron on a low - heat setting if needed. These sheets are built to last, but treating them gently will ensure they stay in top condition for years to come.
