Sewing classes for the beginner to the advanced stitcher!
Computer Patternmaking, Grading, Marking with Optitex
Look for this class again in Spring!
Limited to 4 students/session. Prerequisites: Intro and Advanced Patternmaking (Pattern 1-4)
with instructor Sharon Blair, Northwest representative for Optitex
Go from flat pattern to CAD (computer-aided design) in six sessions. You'll learn to digitize your patterns, modify them, check and correct notches, armholes, necklines and seamlines, create variations and seam allowances. You'll also learn the principles of grading and marking, then apply them to your pattern. Use Optitex 12 -- the same software used by Nike and many designers -- and an Algotex digitizer.
Learn the principles of cardinal points and grade rules on a flat pattern, then move to the computer program and apply them to your pattern. Size grading is the process of increasing and decreasing clothing sizes. Fashion designers work with a patternmaker to develop their first patterns. Samples are made from these patterns and when they are complete and ready to be produced, they need to be graded. The pattern pieces are increased and decreased at specific locations to create each size. Need to know more about grading? Take our basic grading class.
Layout a size run of your patterns for the best fabric usage for your size runs and styles. Learn the difference between mixed, single size and other markers and which to use where. A marker is a layout of the pattern pieces that a cutting service will place on top of the spread fabric. Your goal: The highest fabric usage while conforming to grainline and sizes per your company's requirements. Need to know more about markers? Take our advanced grading and marking class.
