Hi. Thank you for reviewing the Company Cotton Garden Mirage Classic Cool Cotton Percale Sham. We’re glad to hear you are happy with the material and print, but we’re sorry the design has not met your expectations and that the pillows are not staying securely in place. As noted in our product overview, the pillow sham features a 6-inch back closure overlap designed to help keep the pillow in place. An envelope closure sham includes a hidden overlapping fabric panel that creates a pocket-like enclosure for the pillow, providing a more finished and clean appearance compared to traditional pillowcases. To ensure the best fit and security, we recommend fully tucking the end of the pillow underneath the 6-inch flap. This overlapping design is intended to help reduce shifting and keep the pillow secure, even with regular movement or firmer pillows.
