The best sewing machine needles for a beginner

SCHMETZ describes the universal needle in seven words: 'General sewing of knit and woven fabrics. Slight ball point.' That slight ball point is the whole design. A perfectly sharp point pierces the yarns of a woven cloth cleanly and cuts through the loops of a knit, causing runs. A full ball point pushes knit loops aside but struggles to pierce a dense woven. The universal splits the difference, badly enough that a specialist needle beats it on any one fabric, and well enough that it is the only needle a first project needs.

Buy sizes 80/12 and 90/14, and understand what the two numbers mean: they are the same measurement in two systems, metric (NM) and imperial (Singer). An 80/12 is 0.8 mm across the blade. Lighter fabric wants a smaller number; heavier fabric wants a bigger one. Quilting cotton and shirting sew happily on an 80/12. Denim-weight woven, canvas and multiple layers want a 90/14.

The mistake almost every beginner makes is not buying the wrong needle, it is keeping the right one too long. A needle blunts from the friction of passing through fabric thousands of times, and a blunt needle is a leading cause of skipped stitches, snagged fabric and thread that keeps breaking — the exact symptoms people diagnose as a broken machine. Change it when you start a significant project, and change it after roughly eight hours of sewing.

SCHMETZ publishes universal needles from 60/8 up to 120/19, plus assorted packs, twin needles and triple needles. An assorted pack is the right first purchase because it lets you find out which size your fabric actually likes without buying five packs.

A knit fabric is made of loops, not a grid. Push a sharp needle through a loop and you sever it, and a severed loop unravels — that is what a run in a T-shirt is, and it is why a first attempt at hemming a jersey top so often produces a line of small holes along the stitching.

SCHMETZ describes the jersey / ball point needle as 'designed for sewing on knits and some stretch fabrics' and publishes it in 70/10, 80/12, 90/14 and 100/16, plus an assorted pack. The rounded tip slips between the loops rather than through them.

There is a second needle worth knowing about, because people buy the wrong one of the pair. SCHMETZ also publishes a stretch needle, 'designed for synthetic suede or elastic knitwear' with 'a deep scarf to prevent skipped stitches'. The scarf is the groove above the eye where the bobbin hook passes. On a very elastic fabric the material moves as the needle enters, the hook misses the loop of top thread and you get a skipped stitch; a deeper scarf gives the hook more room. So: jersey needle for ordinary T-shirt knits, stretch needle for swimwear, activewear and anything with elastane.

If your machine has been skipping stitches on knit fabric, change the needle before you change anything else. It is the cheapest fix on the list and it is right more often than any tension adjustment.

Hemming jeans is the single most common reason someone buys a first sewing machine, and it is the job most likely to end with a broken needle. The reason is deflection. SCHMETZ's own description of the denim needle names it directly: the needle is built 'for penetrating extra thick woven fabrics, denims, or quilts with minimum needle deflection, reduced risk of needle breakage and skipped stitches.'

Here is what deflection means in practice. A standard needle blade is thin enough to flex. Drive it into six layers of denim at the seam and it bends a fraction of a millimeter sideways. That is enough to make it miss the bobbin hook — a skipped stitch — or to hit the edge of the needle plate hole, which snaps it. A denim needle has a thicker, stiffer blade so it goes where it was pointed.

The point geometry is the other half. SCHMETZ specifies a medium ball point, not a sharp one, which sounds backwards for a tough fabric and is not: denim is a tight weave, and a medium ball point slides between the warp and weft yarns rather than cutting them, which is less damaging to the cloth and less likely to blunt the needle.

Buy 100/16 for jeans hems and 90/14 for heavy cotton, canvas and multi-layer quilting seams. SCHMETZ publishes the range from 70/10 to 110/18 plus a twin denim needle — that twin is what produces the two parallel gold topstitch lines a factory jeans hem has, in one pass.

SCHMETZ describes the quilting needle as having a 'special taper to shaft and slightly rounded point to prevent damage to material sewn in layers'. Both halves of that sentence are doing work.

The taper first. When you quilt, the needle is not going through one thickness of cotton — it is going through a top, batting, a backing, and wherever seams cross, four or six thicknesses of pieced seam allowance. A parallel-sided needle drags all of that with it. A tapered shaft narrows behind the point, so the hole it makes closes behind it and the layers stay put rather than being pushed down into the needle plate.

The rounded point is the same logic as the ball point on a universal needle, applied to a different problem: quilting cotton is finely woven and a sharp point cuts fibers. Over a whole quilt, thousands of cut fibers is a visibly weaker seam.

Two sizes cover it. Use 75/11 for piecing flat blocks, where you want the smallest hole possible, and 90/14 once the batting is in. If you are quilting something heavy — a denim quilt, or a top with dense wadding — SCHMETZ's denim needle is the better tool, because at that point stiffness matters more than taper.

SCHMETZ specifies the microtex needle as a 'sharp point for straight stitches on delicate and microfiber fabrics', in sizes from 60/8 up to 90/14. It is the opposite design decision to the universal: where a universal compromises with a slight ball point, this one commits to being sharp.

The situation where it earns its place is dense, fine cloth — microfibre, lining, cotton lawn, silk. Those fabrics are woven tightly enough that a slightly rounded point can slide sideways along the surface before it finds a gap to enter, which is what puts a barely visible waver in a topstitch line and what puckers a seam.

The 60/8 is the smallest home needle SCHMETZ publishes in any type, and that is the point of it. In fine fabric, hole size is the whole game — a needle too large leaves a permanent perforation line you can see against the light, and no amount of pressing removes it.

Do not use it on jersey. A sharp point through a knit loop cuts the loop, and a cut loop runs. If your project is a mix, that is what the universal needle exists for.

If you have tried to sew visible topstitching in heavy thread and watched it fray and snap every few inches, the needle is almost certainly the cause. SCHMETZ describes the topstitch needle as 'extra sharp with an enlarged groove to accommodate large diameter threads and dense fabrics'.

The groove is the long channel down the front of the needle blade. Its job is to shelter the thread as the needle passes through fabric, so the thread is not scraped between steel and cloth on every stitch. A groove sized for all-purpose thread is too shallow for topstitching thread, so the thread rides proud, abrades, and eventually parts.

This is a genuinely narrow tool and we would rather say so than pad a list. If you are sewing with ordinary all-purpose polyester thread you will notice no benefit at all — a universal needle's groove is already the right size. Buy it the day you buy a spool of heavy topstitching thread, and not before.

SCHMETZ publishes it in 80/12, 90/14 and 100/16 only, which tells you what it is for: nothing light.

Here is the problem it solves, and it is a genuine one: you cannot identify a sewing machine needle by looking at it. Once it is out of the packet, an 80/12 universal and a 90/14 jersey are two small pieces of steel. So people do one of two things — bin a needle that has an hour of life left, or put an unidentified needle back in the machine and spend an evening wondering why the stitches are wrong.

SCHMETZ's description is specific: 'Organize them in the Grabbit myPad by needle type and size. Needle types are color-coded with the SCHMETZ color chart. Simply slip the needle into the appropriate type and size cell on this super thick felt pad. Includes a flower pin to designate the needle that is currently being used in the machine.' It is 6.75 by 6.75 inches, and SCHMETZ states that almost every needle type and size is represented.

The flower pin is the part worth the money. Marking which needle is currently in the machine means you know, three weeks later, whether the needle in there is the jersey needle you used on a T-shirt or the denim needle from the jeans hem — and therefore whether it is the right one for what you are about to sew.

We would not call this a first purchase. It earns its place once you own three or four needle types, which for most people is a few months in. Until then a strip of masking tape on a pill box does the same job for nothing, and we would rather say that than pretend otherwise.
