The topic of permits and licenses has been brought up in the forum. Remember, that to do business, any kind of business, you may or may not need some sort of license. It all depends on where you are selling and local laws. The best place to start searching for an answer would be your local courthouse. On the same note sometimes shows will require special permits to do business in the area. Most of the time this involves paying your taxes on items sold to the local authorities. For out-of-town shows, always check with the show promoters for information about special regulations you may need to follow in order to be within the law.
