• Lemonade stands (typical) and really all types of juice
• Hair wrap and friendship bracelet stands (less typical)
• Home made neighborhood news papers, sold door to door
• Back pack school store (4th grade) - basically, I stole office supplies from my house and sold them to other kids at school
• Magnets (10th grade)
• Senior photos/Head shots
• Pottery

I'm sure there's more I'm forgetting.
