Protection for someone slipping and falling while in your booth at a craft fair. You could be responsible for any injuries sustained as well as damage to another person’s booth.
Protection for your inventory in your home and while at craft shows. This includes theft of your inventory wherever you may be.
Protection for the lost income due to your home being uninhabitable. For example, your home has a fire before your peak season and you need to rent temporary space on a part-time basis to complete your products. The extra expense incurred to rent the space on a part-time basis due to the fire could be covered.
Be informed - Read all contracts with venues since many venues require vendors to accept liability for things like slip and fall accidents that may be out of your control.
Avoid trip and falls - This is the number one exposure for crafters at a craft fair or flea market. Be sure that your area is clear of any and all tripping hazards.
Bring help when needed - Hire a helper for craft fairs or flea markets that may have many attendees. If you are working the booth by yourself, this could lead to theft of your product when you are helping another customer.
