Do some research to determine where you could volunteer during holiday seasons to wrap gifts. Often times, malls or bookstores offer gift wrapping services. Talk with the people in charge to see if tipping is allowed. If not, ask if you could put out a tip jar explaining why you are trying to raise money (i.e. to study abroad!). If you are looking for a bigger project involving gift wrapping, try starting your own gift wrapping service. You could offer to wrap gifts for friends, family and community members and ask them for a flat fee per item or a donation.
