How To Sew A Straight Seam

We finally have everything ready to do the first machine sewing! Once the threads are ready and the pedal is connected, there are no more excuses not to start sewing.

Machine stitching is magical, so enjoy the Disney moment. Naturally, setbacks can arise (and will arise), in the face of which you should not lose your cool, but be patient and not turn sewing into a small hell at home. Most of the time, these problems are related to an incorrect position of the thread, a lever or some other triviality. For the moment, let’s not go on dramas. Let’s start!

STEP 1 Prepare the machine

  • Put bobbin and bobbin, preferably in different colors, to differentiate the seam on each side of the fabric, leaving about 10 cm of each strand outside.
  • Connect the pedal to the machine and to the power outlet.
  • Press the power button, the machine light will come on.
  • Raise the presser foot with the lift lever.
  • Raise the needle with the handwheel.

STEP 2   Put the fabric

  • Prepare a square of fabric, preferably plain colored.
  • Place the fabric under the presser foot and on top of the needle plate with a margin to start sewing 1 or 2 cm from the edge.
  • Lower the presser foot with the lift lever, leaving the fabric trapped.

STEP 3 lower the needle

  • Lower the needle with the handwheel and drive it into the fabric. This will be the exact starting point of the seam.
  • Hold the two strands of thread without pulling or pulling. It is only done during the first centimeters of sewing to avoid knots at the beginning.

STEP 4 Depress the pedal

  • Depress the pedal gently and … the machine starts sewing!

The deeper the pedal is depressed, the faster the machine will sew. At the beginning I recommend you to tread gently to be able to synchronize hands, tissue and mind. With experience you will already increase the pace.

STEP 5 End of sewing

  • As you get to the end of the seam, slow down or even do the last few stitches by turning the handwheel (always towards us) to better control the last stitch.
  • Finish the seam 1 cm from the edge of the fabric.

STEP 6 Raise the needle and foot

  • Raise the needle with the handwheel.
  • Raise the presser foot using the lift lever. We already have free tissue.

STEP 7 remove the tissue

  • Remove the piece by gently stretching it to the left.

STEP 8 cut the threads

  • Cut the threads with scissors or with the machine’s thread cutter.

 The first seam is ready! By using different colored threads, the seam differs on each side. The blue thread is the bobbin thread and the red thread is the bobbin thread.

Seam start and end

How to insure them? If we do not secure the strands at the beginning and at the end of the seam, at any moment it will begin to unravel, and we will run the risk of being half naked in the middle of the street. To avoid such nonsense, the machines have a great feature called “reverse stitch”. When we press the button, the machine sews backwards, laying on top of the stitching you just made. The seam is perfectly secured and we can cut the strands flush with the fabric.

Secure the seam at the start:

  • Sew about 3 stitches by foot or using the handwheel (it is always better controlled when there are few stitches).
  • Lift your foot off the pedal to stop the machine.
  • Press the reverse stitch button.
  • Hold it down while pressing the pedal and the machine sews backward! the 3 stitches (doing it above the first stitches).
  • Lift your foot off the pedal and release the reverse stitch button.
  • Re-sew normally, pressing the pedal. In the images, the presser foot is raised so you can better see the stitches. When sewing and using the backstitch, the presser foot should never be lifted because it is not necessary.

Secure the seam at the end:

  • Sew to the end of the seam by slowing down or using the handwheel for the last stitches.
  • Has the machine stopped?
  • Press the reverse stitch button.
  • Hold it down while pressing the pedal and the machine sews backward! the 3 stitches (doing it above the last stitches).
  • Lift your foot off the pedal and release the reverse stitch button.
  • Re-sew the final 3 stitches, preferably by turning the handwheel.

To practice the straight seams and secure them both at the beginning and at the end, it is ideal to use a piece of light-colored plaid fabric. The gingham fabric, that of the robes and bags of the school snack, is easily found and will serve as a guide to let go with the machine.
