The idea originated with Sarah Young who was inspired by Freecycle (an organization where people can post online things they want, or want to give away for free*).
The uniform swap emerged as an idea to do something more focused regarding back-to-school costs, alleviating some of the expense of purchasing new uniforms and to give everyone in the BHS community a chance to give, receive and recycle. Sarah and JoAnn Lau spearheaded the exchange with support from a team and Martina Harris, head of primary.
* Freecycle organizations exist worldwide. In Bermuda, Freecycling Bermuda exists as a closed group on Facebook for those who want to "recycle" that special something rather than throw it away. Worth a look!
