Dear __________,
Thank you for your generous gift of time to The PTA Clothes Closet. Our non-profit organization is run solely by local volunteers such as you. Because of your assistance, several needy children in our community had the opportunity to try on gently-used clothing, and each select several garments, socks and underwear that they can wear to school. Thank you again for your kind spirit, and stopping by to offer us a helping hand!
