Make monk monks. they are monkeys made from red toed/heeled work socks. It is a child's toy. Very popular at craft fairs, Macy's even had one for sale this past year, a small version as a Xmas ornament.
One vendor at the craft fair made earrings. Tiny little ones that had hearts, or angels or looked like little Xmas ornaments. She put up a sign that said profit to the American Cancer society. $5, boxed, and she sold out.
Earrings are fast and easy. Dangle earrings are cheap and easy. Buy a head pin, load the beads, buy the post or wire, make a loop at the end of the head pin and attach the loop to the post or wire. 5 minutes, plus the time to decide what beads to use. You will need jewelry pliers, round nose ones, about 3-6 dollars each, depending on the brand, and of course the wires or posts, the pins and the beads themselves.
Cookies on a stick, or in a baggie. caramel apples. gourmet brownies. homemade candy[pick simple recipes like Buckeyes, or fudge, or divinity or peanut brittle]. Need a very clean kitchen and good clean technique to sell these.
