Waterhouses and Ipstones Brownies are holding a special service to celebrate the Big Brownie 100th Birthday.
The service will take place at St Leonard's Church in Ipstones on Sunday, June 8, at 11am.
Ann Jackson (Tawny Owl) said: "We are extending a warm welcome to anyone who has been a Brownie, Young Leader or a Guider in either Waterhouses or Ipstones packs.
"We would like them to come along and share their memories of Brownies with us at this special event.
"Our current Brownies will be writing most of the content of the service themselves and doing most of the delivery".
Light refreshments will be served after the service.
