The pattern focuses on actual operation, not drawing pictures every day. The finished pattern must be turned over with fabric to verify its own specifications. The study of technology ultimately depends on the ability to deal with details, not that this style can be done, that style can be done. This is unacceptable. It must be done skillfully, and you should know how to avoid some routine mistakes when making the first pattern.
