I think we all know the potential failings of craft shows. (lack of attendance, people expecting to find "cheap" items for sale, the time involved in set-up, working your boothand tear-down, distance travelled etc.)
I also think that was the birth of ETSY and other on-line seller sites and even (originally) some of the You Tubers looking for prospective buyers.
With all the Youtubers losing their income streams from changes in payouts and in the algorithm, advertising etc.... there seems to have been a revival of the idea of fans or evangelists.
The work and effort of obtaining "new" customers all the time is exhausting and disheartening and keeps "you" from practicing or perfecting your craft, but simply working "on" the business rather than "in" the business... I think the craft show circuit or maybe a better word "treadmill" is the epitome of the "churn" of followers of your craft, meaning that someone coming upon you at a craft show is at the worst case a "one-time" buyer and may never find you again or perhaps only a year later at the next Christmas, 4th of July or whatever show...
Recently I heard about this article (originally posted in 2008 and updated here:

The idea is to make a name for yourself or your product so that you foster followers who become fans and hopefully evangelists.
Obviously there is a current trend of creating "personality" or "celebrity" (I am sure you can think of many of them) but I will suggest that for "the rest" of us, creating a following based on brand or product is more easily achieved than a following based on "personality" or "celebrity". If that is the case, then we have to have a differentiator, something that sets us (the person or the product) apart from other "makers".
So have a read, maybe there is something in there that will help...
