what is a plain seam used for
Plain seams are used to do minor stitching. They can be found in collars and cuffs. They give a clean look after the harder seams have been sewn. When doing this seam, practice sewing straight. Most sewing machines have an indent on the presser foot that you can follow to keep your lines straight. These are the steps to creating a plain stitch: 1  Make a straight line 4 from one end of the sample and cut the piece in half along the line. 2  Mark a stitching line 5/8 from each cut edge.
