Not sure what that even means.
She actually isn't a bad seamstress for being self-taught. It's not easy to design and make a perfectly fitting bikini to your taste from scratch, with no pattern or good examples. Chicks are usually really picky when it comes to their bikinis. Any little imperfections they notice and think everyone else will as well. It was only after searching store to store looking for the perfect bikini without success I suggested she make the perfect style and fitting one herself.
Back when she was taking some nursing classes she started making unique scrubs for herself. Her Mother, who was an RN asked her to make some for her. They caught on with the other nurses who were willing to pay for custom scrubs. She could crank them out fairly fast and inexpensively. I believe they were paying upward of $80 a pop depending on how custom they were.
I think she got bored of it, but she made a nice haul for the time she did it.
