The thing about a website is it should earn you money rather than cost you . Saying that I don’t know much about setting one up but I think of them as a bit like you sitting at an Event for 10 or 12 hours a day but unless your there you won’t sell anything. A website is pretty much un-manned and operates 24/7 . As long as your products are selling this ( imo) will hopefully off set any set up and running costs . People are always looking for one offs that their friends will admire but can never have . Set pieces are a good puller because if a customer loves the 1st piece then then they may well want the set so they compliment each other. So good luck and go for it ..Insurance isn't expensive, my years policy costs me less than £40 and that gives me £5m public liability and £10m personal indemnity cover, a friend of mine is also a turner and woodworker, he does a lot of stalls and has said that occasionally he loses money on the day, it's just the way it goes but it's not often enough to put him off doing it. I'm not sure what my share of the costs are yet for the 2 events I'm going to but I'm going to use them as a guide to if the effort is worth it for myself, I've got a few nice bowls made, needs to make a couple more big ones and maybe some smaller ones then I want to start on small stuff like bud vases that will hopefully do well, I have less than 4 weeks to go so may end up having to take stuff from the shop for the 2 days, also need to get a card reader, I've lost out on sales before due to not having one.
Etsy is a possibility but I begrudge giving them their cut and their t&c seem to be making it harder and harder on the sellers, not to mention the fact it was set up for creative to sell their craft and now it seems to be mostly mass produced tat.
Need to look into the costs etc around having my own website, I know someone that can set it up for me so just need to sit with them and go through everything.
