I started working on sticks a few years before I retired. It was purely a pastime. I'd just sit on my garden bench on sunny weekend days, and whittle away. When I approached retirement, my wife was concerned that I might "veg" out. Just become unmotivated. She suggested that perhaps I could turn stick making into a part time job for myself.
I did some speculation, ran some numbers, and decided that at best I would make no more than a fraction of minimum wage. If I ever make any money from the work, I'll be thrilled. If I ever get enough sticks that I'm happy with, I might pay for a booth at a craft fair. Or even a table at a flea market. Having sold paintings and drawings in the past, I can tell you it is immensely satisfying and motivating to make even modest sales.
So, unless you have already committed to the fair, and have a sufficient stock, I'd suggest you hang back. If you loose your motivation, there goes the creativity. That means you will be turning out items that are non-necessities which need to be as interesting and attractive as possible.
