How to Use a Sewing Machine: A Calm Beginner's Guide

A sewing machine has a reputation for being fiddly and temperamental, and a lot of people who would happily learn to mend never get past the wall of dials and levers on the front. Here is the reassuring truth: a machine is not one complicated thing, it is four or five very simple systems working together. There is a lower thread on a bobbin, an upper thread that runs down to the needle, a foot that holds the fabric, and a set of little teeth that pull the fabric through at an even pace. Once you can see those systems separately, the whole machine stops looking like a control panel and starts looking like a tool.

It is worth learning, because the sewing machine is the workhorse of make-do-and-mend. A hem that comes down, a seam that splits, a patch on a knee, a bag of curtains to shorten: all of it is faster and stronger by machine than by hand. For the jobs where a machine is overkill, hand stitching still has its place, and our guides to mending clothes and darning socks cover those. But for the bulk of household mending, this is the tool that earns its keep on the table.

The parts that actually matter

Ignore, for now, the parts you will not touch. These are the ones that do the work.

• The bobbin is the small reel that holds the lower thread, the thread that forms the underside of every stitch. It sits in a bobbin case under the needle plate, either dropping in from the top or loading in from the front.
• The needle is removable and consumable. It clamps in at the top and you will change it often. Blunt or bent needles cause more trouble than almost anything else.
• The presser foot is the little metal (or clear plastic) foot that lowers to hold the fabric flat against the machine while you sew. It lifts on a lever behind or beside it.
• The feed dogs are the tiny teeth that poke up through the needle plate. As the machine runs, they grip the underside of the fabric and walk it backwards, a set amount per stitch. Your job is to steer, not to pull; let the feed dogs do the feeding.
• The tension dial controls how tightly the top thread is held as it feeds. Balanced tension makes the top and bobbin threads lock neatly in the middle of the fabric. Too tight and the seam puckers; too loose and the stitch will not hold.
• The stitch selector chooses the stitch, most often a simple straight stitch or a zigzag on a basic machine. Alongside it you will usually find a stitch-length control, and on many machines a stitch-width control for the zigzag.
• The hand wheel (some makers call it the flywheel or balance wheel) is the knob on the right-hand end. Turning it by hand raises and lowers the needle precisely. Always turn it towards you, never away.
• The reverse lever or button runs the stitches backwards for a few stitches. You use it to lock the thread at the start and end of a seam so it does not unravel. Some manuals call this backstitching.

That is the whole cast. Everything else on the front, the extra stitches and the fancier dials, is a variation on these.

Winding and inserting the bobbin

The bobbin has to be filled with thread before it can make the underside of your stitches, and it is filled by the machine itself. Put a reel of thread on the spool pin, lead the thread around the small bobbin-winder tension disc near the top, and wind a few turns around an empty bobbin by hand or through its little hole. Pop the bobbin onto the bobbin-winder pin and slide it across until it clicks or locks. Then press the foot pedal gently and let the machine spin the bobbin full. Start with an empty bobbin so the thread lies evenly, and stop when the thread is almost level with the edge of the bobbin, not overflowing. Slide the winder back, lift the bobbin off and snip it free, leaving a short tail.

Now seat it. On a drop-in machine, lay the full bobbin into its recess under the needle plate and lead the thread through the little slot so it catches in the bobbin tension; on a front-loading machine, the bobbin goes into a removable case first, with the thread pulled through the slit in the case. Which way the bobbin should turn as it unwinds depends on the machine, so follow the small diagram on the machine or in the manual. Get this right and the lower half of every stitch is sorted.

Threading the top thread: the order matters

This is the step that defeats most beginners, and almost always because the order is wrong or a stage is skipped. Do it slowly and in sequence, and crucially, raise the presser foot first. Lifting the foot opens the tension discs so the thread can drop between them; with the foot down, the discs are clamped shut and the thread simply rides over the top, which is a leading cause of thread nests underneath.

Thread the top thread in order

1. 1

   Raise the needle and the foot

   Turn the hand wheel towards you until the needle and the take-up lever are at their highest point, and lift the presser foot lever.

2. 2

   Spool and first guide

   Put the thread reel on the spool pin and lead the thread across into the top thread guide, following the numbers or arrows printed on the machine.

3. 3

   Down and around the tension discs

   Draw the thread down the channel on the front, around the bottom of the U and back up. This is where it seats between the tension discs. It only seats properly because the foot is up.

4. 4

   Through the take-up lever

   At the top of that U, hook the thread through the eye of the take-up lever. Missing this lever is the single most common threading mistake.

5. 5

   Down to the needle

   Bring the thread back down through the lower thread guides just above the needle.

6. 6

   Through the eye

   Thread the needle's eye, usually from front to back, and pull a tail of about 10 to 15 cm through. Use the built-in needle threader if your machine has one.

Bringing the bobbin thread up

You have two threads now, top and bobbin, but the bobbin thread is still hidden under the needle plate. To marry them, hold the top thread loosely in your left hand and turn the hand wheel towards you through one full turn. The needle dips down, catches the bobbin thread and brings up a loop as it rises. Slip a finger or a pin under that loop and pull it out into a tail. Lay both threads back and to the left, under the presser foot, leaving a few centimetres trailing behind. Both tails behind the foot before you start is what stops the first stitch snarling.

Your first straight stitch

With both threads sorted, practise on a doubled scrap of plain cotton before anything real. Slow and steady wins here; the foot pedal is a dimmer switch, not an on-off, so ease onto it.

Sew your first seam

1. 1

   Position the fabric

   Slide the scrap under the raised foot so the needle will come down about 1.5 cm in from the raw edge, using the guide lines etched on the needle plate to keep it straight.

2. 2

   Lower the foot

   Drop the presser foot onto the fabric. This is what applies the tension, so it must be down before you sew, even though you thread with it up.

3. 3

   Backstitch to lock the start

   Hold the reverse lever and sew three or four stitches backwards, then release it. This locks the thread so the seam will not pull undone.

4. 4

   Sew forward, guiding gently

   Ease onto the pedal and let the feed dogs pull the fabric through. Rest your hands lightly either side to steer along your line. Do not pull or push the fabric, or you will bend the needle and pucker the seam.

5. 5

   Backstitch and stop

   At the end, hold reverse for three or four stitches again to lock it, then stop. Turn the hand wheel towards you to lift the needle to its highest point.

6. 6

   Lift, remove and snip

   Raise the presser foot, draw the fabric back and to the left, and cut the threads, leaving short tails.

Do that half a dozen times and your hands will start to know the rhythm. Straight lines first, then gentle curves, then corners (needle down, foot up, pivot the fabric, foot down, carry on).

Zigzag, stitch length and tension

Once straight stitch feels natural, the zigzag is the next stitch worth knowing. Because it swings from side to side it stretches with the fabric, so it is the stitch to use on knits and anything that needs give. It is also the everyday way to stop a raw edge fraying: run a zigzag along the cut edge of a seam allowance and it binds the threads, doing the job of an overlocker on a budget. The stitch-width control makes it wider or narrower.

Stitch length sets how far the fabric moves per stitch. A medium length suits most general sewing; go shorter on fine or delicate fabric for a neater, stronger seam, and longer for tacking (loose temporary stitches) or gathering. Tension is the one people fear, but the rule is simple: if the stitch looks balanced and the same on both sides, leave it alone. If the top thread is pulling the seam tight and puckered, ease the tension dial down; if loops show, the tension may be too loose or, more often, the top thread has slipped out of the discs. Always test tension changes on a scrap of the same fabric, and change one setting at a time.

Common beginner problems and how to fix them

Nearly every early frustration is one of three things, and each has a clear cause.

Puckering (the seam gathering up so the fabric will not lie flat) is a tension issue: the top tension is too tight and drawing the fabric in. Turn the dial down a little and test on scrap. On fine fabric, a shorter stitch and a finer needle also help. Thread keeps snapping usually points to tension set too high, a rough or old thread, or a nick around the needle plate. Fabric will not feed normally means the feed dogs are dropped (there is often a switch for that, used when free-motion quilting) or the stitch length is set to zero.

A gentle word on choosing a machine

If you are buying to learn and to mend, a simple mechanical machine is friendlier than a computerised one bristling with stitches you will never use. A dependable straight stitch, a zigzag, adjustable stitch length and a reverse lever will carry you through the overwhelming majority of homestead mending. Fewer dials means fewer things to misjudge and a shorter walk from box to first seam. A basic starter kit alongside it, with a few spare needles, extra bobbins, a seam ripper and some general-purpose thread, is money well spent. Buy the machine you will actually thread and use, and leave the feature list to the sewing-room enthusiasts. The point is a mended hem tonight, not a control panel to admire.
