No sewn product can be made without threads. As big an item like tent and as small a product like collars, all need appropriate threads for sewing them up. Sewing threads are constructed for smooth stitching that will not break or become distorted for the entire life of the sewn product. Sewing machines are used to join the parts with the sewing thread in a process called Sewing. Threads' main work is to hold together various parts of the sewn product. However, threads are also used for crafts such as in embroidery for making embroidered clothing and other embroidered patterns home furnishings, bags etc. Other than embroidery, various other crafts like crocheting also use threads in good amount.
