Pattern grading is a very important part of the clothing production process. It is the process of scaling pattern sizes up and down from the base size. In order to learn pattern grading it is useful to have a basic understanding of patterns, but it is not necessary to be an accomplished pattern cutter. It is a very useful skill both for the fashion professional and the home sewer. It is also useful for any fashion startup on a shoestring budget as it can save a considerable amount of money to be able to grade your patterns.
