As a Fashion Professional, a basic understanding of patternwork and standard Industry procedures in this regard is key for success...

Not only because 'knowing' will save you valuable time communicating back and forth with your those involved in the process (pattern makers, technical designers, cutters, sewers, etc) but also because a lack of this knowledge will make you seem unprofessional, no matter how committed you are to your brand.

The more professional you come across, the more seriously you are taken!
