Think about which people you plan to sell to. Is this the sort of fundraising for a church that will target the congregation directly, asking them to give their support after services or at church events? Or will you be doing the kind of fundraising for a church that will require a team of parishioners to go out into the community and ask for support in that way? Whatever you decided to do, your fundraising will need to match up to your customers.
How much money do you need to make while findraising for a church? This can affect what sorts of fundraising for a church you want to do. If you need to raise a significant amount of money, obviously something like lollipop fundraisers wouldn't work out that well, because you'd have to sell them for months on end to make any real progress. On the other hand, if your fundraising for a church is just going to pay for moderate expenses, then something like candy bars could work for you. Some fundraising for a church activities are suited for larger efforts, and some for smaller. If you have a lot of people who are helping with the fundraising for a church, you could go all-out and do something like pretzels, which suit groups with more selling power.
