If you want a job as a sample maker you should have samples of your samples! Many businesses and fashion designers are on the lookout for sample makers as they need them before launching a new design. Most sample makers train on the job although if you have previous experience this can put you at the top of their candidate list. You might start out by applying to jobs in the manufacturing to develop a better knowledge of the process from design to production. Once you gain more knowledge then move on to working with an up and coming new fashion designer.
