A patternmaker is usually (in my field anyway) someone who can create clothing patterns by either drafting (using measurements) or draping (using a dressform or in rare cases like custom work using a live body). The company I sent my resume to is a handbag company but the patternmaking princples still apply, they also use a CAD system that I am familiar with.
The spam email that I got apparently came from a site that I had looked at and maybe even gave my email too. But in order to have full access to the jobs they said they had they wanted $14.95 a month. Yeah right! I'm not paying that. But they sent me an email with a minimun of info (title of job and location) and from that I was able to google and find the company website and their employment opportunity page. I'm one smart cookie. lol
