No matter which school you go to, you should consider it on the spot. Clothing printing must be practical. Generally speaking, the method must be correct, not just drawing. You should have finished products at once, there is no need to consider dozens of people in a class. Clothing printing is a major that needs details. You can find a job without common sense of clothing printing, but you must do the details well. A class can't have too many people. It's about practical painting. You can't see how the teacher draws, let alone how the teacher skillfully handles the details. Generally, about ten people are the best, so we can go on a field trip from these aspects.
However, Gao Hong's two books, Clothing Structure Design and Its Application and Clothing Factory Pattern Collection, are practical and worth reading. They are both 139 yuan. You can go to Baidu to look at the encyclopedias of these two books.
