I suggest you take it as a career, or you can't do it well. A good pattern designer can't do it in three to five years.
Looking for a temporary job, it is recommended not to look for a job related to clothing, because there are many jobs in clothing and the working hours are very long. Once I work, I'm afraid I won't have time to learn anything else.
I've been doing it for almost 20 years. I hope you can refer to my opinion.
