When organizing youth fundraising ideas, you will need to think about how many kids you're working with, and how much money that group needs to raise. Also take into account the size of your fundraising team, so you know how many people will be helping out. If you're concerned about not having that many people, don't panic, because there are a wide variety of youth fundraisers that work tremendously well for small groups, even some with profits that can go up to 90%. So the size of your group shouldn't be a factor - just get everyone motivated and think about the activities that would probably work best for them.
Most fundraisers can be adapted for various groups and types of situations, so you shouldn't worry too much about choosing the "wrong" youth fundraising ideas. If you're curious about a certain product or activity but not sure it will suit your group, just contact your fundraising consultant, who will help answer any questions and get you on the right track. The important thing is to enjoy yourself, because no matt which fundraiser you choose, you're bound to have great fun with it, and you'll be doing some important work that will benefit kids. Good luck!
