Is there any good clothing design software?

Pattern Master is pretty good. Ther's also Wild Ginger. And Many business use autoCAD and program it for pattern making, which is okay of you don't mind spending the money on a CAD developer. It depends on the application, if you are making patterns for yourself or a small client base; or if you are making patterns for large scale manufacture. There are different license agreements for software depending on the business size and you do need to follow the license guidelines. I am not a fan of software based pattern design, but I tend to be old school in my method of working.  more
