Also your donors don't only have to consider a cash gift, they could leave a % of their property or even specific items. One of the best legacy gifts we have come across was a charity being left "the second best Hoover"!
Finally, never underestimate your supporters. Just because they haven't made large donations, doesn't mean they aren't thinking of you in their will. Recently an organisation we know was left a huge gift from someone that had previously donated very small amounts once a year.
Legacy income really can have the power to completely transform organisations... so think about how you can incorporate a legacy ask into your programme.
