The summer fair raised £6,700 while celebrating the trust's 60 years in Cheadle Hulme.
Wendy Bray, Seashell Trust fundraiser, said: “We had hundreds of visitors, including lots of our students and their families, as well as members of the local community, our volunteers and supporters.”
Entertainment included LL Extreme Cheerleaders and the Alderley Scout Band. Caremark, a local home care provider, ran a sweet stall and lucky dip.
