Contract sewing jobs focus on the production of clothing and other items using a sewing machine. Your duties and responsibilities as a contractor in this field vary depending on the details of each project on which you work. A client can ask you to sew materials for retail, custom designs, or personal use. However, as a contractor, you are not often responsible for mass production jobs. Your client should supply details for the project, such as the type of fabric, measurements, and required design elements. As a seamstress, you create a price for the project and ensure that you can complete the work by the deadline.
