Textiles+-+Joining+&+finishing+techniques

Introduction Seams are the fundamentals of sewing and there are many different types, the basic seams work well for most purposes but knowledge of others can help you to make a more professional job of a textiles product. 1 Before starting to join fabric and forming a seam, you have to know about the **seam allowance**, that is the space between the sewn line and the raw edge of the fabric. Many patterns allow for 1.5cm (1/4 inch) or 1cm, some even require 2cm and allow for trimming down afterwards - read pattern instructions carefully. When sewing the seams on the machine, there is an additional guide on the machine throat plate, with incremental markings for you to guide the raw edge of the fabric in order to make seam a consistent distance from the edge.

You should make samplers for each of the above techniques - clearly labelling them, taking photos of the processes, tools and equipment, and sewing machine settings. Use calico and coloured thread to make each of the samplers. Repeat some of the seams with different samples of fabric: Make notes of settings, techniques, and suitability for the fabrics.
