Craft sales at farmer's market
Girls prepare during the spring making crafts and then sell at a booth at a farmer’s market during the summer. Some examples include homemade candles or sachets for drawers. In addition they can do plant sales.
Make a game for your town. Invite different organizations to "buy-in" to the game and sell at Christmas or during another holiday season. No out-of-pocket money is needed because you can get a company’s donations in order to make the whole game.
Make breads to sell as teacher gifts or for family/friends. Can be holiday, end-of-year, Valentine’s Day, or around any other time. Pre-sell so that you don’t waste money on extras. Girls can make small or regular sized breads. Suggested selling price: $5-$10.
Make headbands or feather clips. Purchase supplies inexpensively at craft stores and sell for $2 each.
Girls can design a 12-month calendar. Adults can ask companies to sponsor each month (girls can draft the letters) and by making the donation to the council they can be tax-deductible. Get a company to donate/offer a discount for making the calendars for additional savings. Suggested price: $13/calendar.
Collect recipes from members of the community and include great photos. You can do this around a theme or they're good to sell any time of year.
Make these out of bandanas and sell for $10-$13 each (upfront cost is approx. $2-$3 each).
