Don't forget to buy drinks to sell at your garage sale. Either sodas, bottled water, or hot chocolate (depending upon our TX weather!). You can get them so cheap, and make some major profit off of them! Even donuts and candy bars are good sellers depending upon your turnout.
The fall fundraiser at my childrens' preschool has always been butterbraids. They make a killing off of them. I would definitely keep this for future reference. They are great to sell right before Thanksgiving for people to have around the holidays. Go to www.butterbraid.com for more info.
You could also have members or other WAHM make up gift baskets for auction. I might be interested in donating one, or items for future meetings.
