redson pattern help me to keep my regular customers while others just use yonex pattern (4 knots) or lining/victor (I don't know correctly the name but it's 2 knots and people call it "basic/traditional", from 9 to 12 and back to 10 of the main and then go to the cross). The customers go to my shop because of my pattern (~ 80% of my area).

But it's take me more time than the traditional patter. It's about 40 minutes, if I go for traditional pattern, I can finish 1 racket under 25 minutes.

At the beginning, I go to the customer's house to take and racket and give back about 5pm (badminton time), it gave me an initial advantage, but "the water can both lift a boat and also sink it", I began to feel overwhelmed and unable to continue that way, number of customers was lower then. But I'am happy for not going like a dog, haha.

In Canada, 40 rackets per month can live well (basic living needs, the lowest level of Maslow's hierarchy), but in Viet Nam, I have to find a way to do three or four times as much work to earn enough to live on. It's not a matter of time; the problem is that profits are too low due to excessively low income.

About the video on youtube that show us a completed racket can take about 16 or 20 minutes, It's just like cooking a dish faster than a restaurant does, it's just a video (a show for us to watch). Preparing a delicious meal in a high-quality restaurant requires much more—ranging from food hygiene, ingredient inspection, and a clean kitchen to ensuring diners enjoy the food and retur.

It’s the same with badminton racket stringing; I could finish a racket in 20–25 minutes, but I’m not sure the customer would come back.

In some YouTube videos, the work seems really sloppy—they’re just focused on finishing the video as quickly as possible.
