Doing free soap making demonstrations is a win-win situation for the sponsor and the crafter. Many organizations have loyal members who are looking for new ideas and crafts. This is where you, as an experienced crafter, step in. You offer to do a free soap making class for the group and the charity/organization charges a nominal fee for any member wishing to attend the class. They provide the venue and you provide the expertise. They get to raise some much-needed funds, and you get a new customer base with a very loyal following.
