Before you start	100	developers	start pattern	A guide to go over a few things you should know when you start working with our core library	Understand that FreeSewing provides parametric pattern design Understand that FreeSewing uses SVG Understand the coordinate system Learn that we use millimeter internally Learn about Bézier curves

Drawing lines and curves on paper is a skill most people have been practicing since kindergarten. In FreeSewing, we draw lines and curves with code, which is a bit more abstract but doesn't have to be complicated once you understand a few basic building blocks.

Understanding the concepts that are involved in designing sewing patterns in code will pay dividents later. That is why we recommend you familiarize yourself with the following topics:

There's no need to know everything

FreeSewing sits at the intersection of the world of makers and developers. If your background is in development, you will need no explaining what SVG is, but might not know much about designing sewing patterns. If on the other hand your background is in sewing or pattern design, you might wonder what the heck Node JS is and why you should care.

Few people straddle both worlds, so as you start using FreeSewing, chances are you'll learn a few new things along the way.
