Selecting the proper thread for your product is achieved by first determining the end-use requirements of your sewn products including: seam strength requirements, stitch & seam design, optimum stitch length, and the normal life of the product. Other factors that are considered include the type of material being sewn, the type of sewing machines being used, conditions under which the product must perform, and cost effectiveness.
