Now I have nearly finished our house and gite ,I have started making a few garden ornaments and just thought I might make a stock to take to a local car boot when they start up again ...question is can I ??
Strictly speaking you can't sell new stuff at a car boot, you could mix it in with your second-hand stuff once or twice just to see if there's any interest, get a bit of feedback...then you'll have to register as an Autoentrepreneur or whatever. Plus you're only allowed to two or three car boots a year, more than that and they'll consider you a professional seller.
not sure you can without a licence as you're making things to sell rather than selling off old unwanted things... but I'm sure there are others here who are better informed and who can point you in the right direction.
