Send thank you notes. Comply with any reporting requirements they might have. Let funders know how your event or project turned out. If possible, send a picture or newspaper clipping. Follow-up is important not only because it helps funders feel positive about their contribution, but also because it keeps the doors open for future support.
All communities have a variety of potential funding sources.
Many are well-known and obvious. For those that are less visible, use your network of parents, teachers, and others to brainstorm possible funders with whom they might have connections, such as employers, religious groups, organizations and clubs, or merchants. Try to match your needs with the interests and assets of these groups. Start close to home. Or try bringing your larger school corporation aboard as a partner, i.e., Title I may have funds to contribute if the families of Title 1 students will also benefit.
