I would say if you re good looking try a dating service. Offer three girls the chance to go out with you for $20, unless that is illegal, sounds like a dating auction to me though. Other than that the best bet might be T-shirts if you still have time to order them and of course some sort of chocolate food. But sell the chocolate desert with the option to deliver it to someone else with a message. That could be worth twice the price and for the cost of a slip of paper. Good luck either way.
hemp jewelry is really easy to make (you could probably look it up online) and you could by the hemp and beads for pretty cheap at a hobby store. normally that type of jewelry is overpriced so if you sell it for a reasonable price it could probably do pretty well. plus girls and guys can both wear it.tip: if you use thick hemp (which would probably be better for the male crowd), also use thin hemp for the middle section to make stringing beads easier. also, make sure the beads have large holes.
