I would suggest doing as birthday parties, parents are always willing to shell out a little more when its thier childs birthday. Personally I’m always looking for new birthday party otions for my kids. I teach a kids decorationg class at my sons school (its volunteer so I dont make anything the pta just reimburses my costs). The kids really love working with fondant and cupcakes best. Most of the kids have a hard time with icing cakes, so I stick to cookies & cupcakes. I teach them basics such as mandling the bag, using tips, borders, drop flowers etc. They get to bring home whatever they decorate.
