In reality, there is no single "right" church fund raiser, so go ahead and explore all your options instead of thinking that you have to do the same church fund raiser year in and year out. Of course you want to do a fundraiser that works, but there is also the issue of things getting old and tired, and if your traditional church fund raiser has been performing less well recently, it may be time to change it up a little.
The biggest factor is to match your fund raiser to the size of your group. Smaller church groups may feel like choosing a church fund raiser that will offer high profits. Things like scratch cards or pizza fundraising cards are wonderful for a small church fund raiser, beacuse they really give the church a chance to make a respectable amount of money. If minimum orders are a concern, you may want to go with a church fund raiser that has the lowest possible minimums - a cookie dough fund raiser can be a very popular choice, and the minimum orders are very low.
You have an endless amount of choices for your church fund raiser, so don't feel down if the first couple of things you look at don't work out for you. Browse through church fund raiser pages, choose one that fits well with your group, and start to get excited that your church fund raiser has every chance in the world of being a huge success.
