Ever tried selling stuff on the road?

Hey, stupid first time traveller question coming up

I'm a brit, planning a 2 month trip to the states this summer (west coast). I've budgetted carefully and I've got enough cash, plus some extra, just in case! However, I will be travelling on a shoestring and I was wondering about supplementing myself by selling handmade hemp jewellery on beaches and streets and the like. I can also do a bitchin' hair wrap, which I thought might be good for marketing to tourists - and both are things I can easily and cheaply get the materials for anywhere.

That said, I have no idea if that's at all feasible. I've seen people do it on other beaches quite often, just putting out a blanket and some wares, but I don't know if there are likely to be more restrictions on US beaches, if I'm likely to get moved on quickly... I'd appreciate any insight at all
