A-N give Public and Product Liability insurance as well as Professional Indemnity (in case someone thinks you may have copied their work and tries to sue you) as part of the membership sub. Those insurances do not give cover for theft, goods in transit etc, they just give cover if your products cause harm to someone e.g. the dye you used causes an allergic reaction to someone, or if you unintentionally cause harm to someone, e.g. picture glass breaks at a show and cuts someone, or your display falls and hurts someone etc.
A-N use Hencilla Canworth for that insurance. It was set up because it used to be very hard for artists etc to get proper insurance cover. They also offer insurance for artists, designers, makers etc for cover of stock, studio equipment and other business insurance needs. There are subsidised rates for members of A-N or standard rates if you are not an A-N member. They offer various packages or they can make you a bespoke insurance. Have a look on www.a-n.co.uk for more information about the insurance options.
I just have A-N membership so get the free cover. I have used Hencilla Canworth through A-N for just art exhibition cover as well which can last up to one year at a time for the shows you do. They give cover for the full value of artistic works if they are stolen, damaged etc at an exhibition whereas a lot of insurers only cover for direct costs, i.e. the cost of replacement materials. They give goods in transit cover, which can be very hard to get at a good price, and all sorts of things you probably never thought of.
I also have a working from home insurance policy from AXA which gives £1,000 of all risks exhibition cover as part of the policy as well as all home contents cover and standard business cover. I am not sure what policies they are offering at the moment, I think mine keeps going because I have had it a long time and I think they may offer something slightly different now.
It’s worth checking with the craft show organisers exactly what insurance they give you, or not, so that you can then know what your real needs are.
Hope this helps.
