If like most people who sell soap it is an "extra" income and doesn't have to pay a mortgage/utilities then you get to develop your own business model. I like people and love the craft fair venue. I am fortunate to live in an area with yearly shows and I do 5 shows in the fall. I don't have a website and don't do wholesale. It works because it fits what I love. I have made many friends and have a very faithful customer base developed over the years that I see each year. I started when I retired in 2006 and will stop when the aches/pains make setting up the booth too difficult.
I'm just a hobbyist at this point and do not sell so take this for what it's worth.
But I have to agree with the above comment.
I think you have to pick a business model and work to that.
your business model maybe that you have a full-time job and just do a couple craft shows a year. If you make a little money doing that and you're happy with it then I think that's good.
I think that's also a great way to get started to see if you would want to do this as a full-time business or if you are able to do this as a full-time business.
I don't think a person necessarily needs to jump in with both feet and try to make a living pay your mortgage and all your bills doing this.
Doing a couple of craft fairs/farmers markets/ shows here and there to get your feet wet to see if people like your product and if you can actually make a little profit doing it is likely a good way to start.
Doing a website, Etsy store, etcetera all require that you keep a certain amount of product on hand continue to make product and the cost associated with it.
But when you do a craft fair your only selling what you have already made and packaged up.
And if it doesn't work out and you lose a little money at least you're not paying a monthly fee for a website and all that goes with it.
I know a lot of people say the market for soap is saturated.
But do all of those people live in the area you live in?
Are all those people making the same kinds of soap as you?
I know some of the soaps I'll be making this summer will not be the same soap everybody else makes. Mainly because I like to use oils infused with wild local herbal products.
So I think it depends on a lot of different factors on whether you'll make money but I think testing the waters with a couple of craft fairs or shows will give you an idea whether you really want to do it and whether you can make a profit at it.
This is just my two cents take it for what it's worth.
