How To Sew Straight – Step by Step Instructions

Know Your Sewing Machine


Before you learn to sew a straight line, it is important that you understand your sewing machine. It is the first thing that you should learn before even stitching anything ahead.

Go through the machine manual and understand the working of each and every part and dials. Get to know how to adjust stitch length, thread tension, and seam guides.

Take any fabric and place it under the pressure foot. Now lower the needle all the way down into the fabric. Remember to start every stitching like this only.

Use the speed controller and stitch randomly for a while to understand the pressure you apply on speed control.

In a Nutshell:

  • Read the instruction manual
  • Understand the machine parts and their working
  • Practice with a speed controller

Follow The Pressure Foot Edge


The easiest way to sew a straight line is just by following the edge of the pressure foot.

  • Take a piece of fabric and place it under the pressure foot.
  • Align the fabric edge with the edge of the pressure foot.
  • Now bring the needle down all the way inside the fabric.
  • Use the speed controller and start sewing straight.
  • While sewing, make sure that both the edges of pressure foot and fabric are aligned together.
  • Sew a couple of inches straight then reverse sew to lock the stitching for strength.
  • Repeat this entire process several times until you get a hold on it.

Set Up The Seam Guide


Learning and setting up the seam guide is another way to sew a straight line every single time. Remember I told you to go through manual to learn the markings on your sewing machine.

Seam guidelines on your sewing machine near are needles. They are helpful in mapping the edges and helps your stitch straight.

  • Place the piece of fabric on the machine and align the fabric edge with seam guides.
  • Start sewing and watch closely the seam guides.
  • Avoid looking at the needles and look if the fabric is aligned with the line or not.
  • It will help you achieve straight seams every time after a couple of practice.
  • While stitching, you can maneuver through these seam guide lines to make sewing patterns.
  • However, initially, you stick with stitching straight line.

Stitching Straight Around The Corner of a Fabric

As a beginner, you might find it complicated to sew at the corner of a square or rectangle fabrics. But again it is quite easy to sew a straight line around the corners.

  • Keep stitching almost until you reach the end of your fabric.
  • But leave around 1/4″-1/2″ of space between your needle and the very edge of the fabric (or your desired length)
  • Now, remember to keep your needle lowered all the way into the fabric.
  • Then lift the pressure foot and turn your fabric and adjust its edge again with seam guides and align the edge.
  • This way the needle will hold the fabric on its place and you will be able to turn the angle of stitching by 90 degrees.
  • Lower your pressure foot and continue sewing in this new direction.
  • Use the above step all the time when you want to change the direction of sewing.
