Knitting has a reputation for being complicated. It isn’t. There are two stitches — knit and purl — and almost every pattern you’ll ever follow is a combination of them.
What makes knitting feel complicated is that beginners often start with the wrong materials, and later find their finished garment is two sizes off because they skipped a twenty-minute step.
This guide covers materials, the core techniques, gauge, and how to fix things when they go wrong. It’s part of our wider knitting and fabric section.
Starting With the Right Materials
Material choice does more for a beginner than technique does.
Needles: US 7–9 (4.5–5.5mm). Large enough to see clearly, not so large that stitches become unwieldy. Bamboo or wood is better than metal to start with — the surface has more friction, so stitches don’t slide off while you’re still developing tension.
Yarn: DK or worsted weight. Chunky yarn magnifies every tension error; very fine yarn makes loops hard to see. DK and worsted sit in the middle where stitch behaviour is easy to observe.
Colour: light and solid. A cream or grey worsted is genuinely the best first choice. Dark or variegated yarn hides your loops, and textured yarn makes it hard to see where the needle needs to go.
Also useful: a tape measure, stitch markers, scissors, and a blunt darning needle for weaving in ends.
Yarn Weights
| Weight | Typical needles | Gauge (sts / 4in) |
|---|---|---|
| Lace | US 000–1 | 33–40 |
| Fingering / sock | US 1–3 | 27–32 |
| Sport | US 3–5 | 23–26 |
| DK | US 5–7 | 21–24 |
| Worsted / aran | US 7–9 | 16–20 |
| Bulky | US 9–11 | 12–15 |
| Super bulky | US 11–17 | 7–11 |
Not every ball band names a weight category — European yarns in particular often skip “DK” or “worsted” and print only the gauge and suggested needle size. That’s actually the more useful information. Match the gauge and the weight name stops mattering.
The Core Techniques
Five techniques cover nearly everything.
1. Casting On
Creating the first row of stitches. Two methods are worth learning first:
Long-tail cast-on — the common default. Produces a neat, moderately stretchy edge. Allow roughly 1 inch of tail per stitch, plus a few inches spare, so you don’t run short mid-row.
Knitted cast-on — builds each stitch using the knit motion itself, so it reinforces the stitch you’re about to learn. Requires no pre-measured tail, which makes it forgiving.
Cast on loosely. A tight cast-on pulls the bottom edge in and is the most common beginner frustration.
2. The Knit Stitch
The foundation. Worked repeatedly on every row, it produces garter stitch — a reversible, ridged, flat fabric that doesn’t curl.
Garter stitch is the ideal first project fabric precisely because it doesn’t curl and looks the same on both sides.
3. The Purl Stitch
The reverse of a knit stitch. Alternating knit rows and purl rows produces stockinette stitch — the smooth “V” fabric of most shop-bought jumpers.
A useful way to tell them apart: think of the yarn at the needle as a neck. A knit stitch looks like a V-neck; a purl stitch looks like a turtleneck.
Stockinette curls at the edges — inherently, for structural reasons, exactly like machine-knitted jersey. That’s normal, not a mistake.
4. Increases and Decreases
Shaping. The common ones:
- k2tog (knit two together) — decrease, leans right
- ssk (slip slip knit) — decrease, leans left
- yo (yarn over) — increase that creates a deliberate hole; the basis of lace
- m1 (make one) — increase without a hole
5. Binding Off (Casting Off)
Finishing the edge so it doesn’t unravel. Bind off loosely — a tight bind-off puckers the top edge and, on a jumper neckline, can make it impossible to get over your head.
Basic Fabrics
| Stitch pattern | How | Character |
|---|---|---|
| Garter | Knit every row | Reversible, ridged, doesn’t curl |
| Stockinette | Knit one row, purl one row | Smooth V face, curls at edges |
| Rib (1×1, 2×2) | Alternate knit and purl in the same row | Stretchy, recovers, doesn’t curl |
| Seed / moss | Alternate knit and purl, offset each row | Textured, reversible, flat |
Rib’s stretch and recovery is why it’s used for cuffs, collars and hems — exactly the same reasoning as in machine-knit garments.
Gauge: The Step Not to Skip
Gauge is stitches and rows per 4 inches (10cm). It’s the detail beginners skip and later regret, and the maths shows why.
Say a pattern is written for a 40-inch chest at 5 stitches per inch, so you cast on 200 stitches. If you knit slightly loosely at 4.5 stitches per inch, those same 200 stitches now measure 44 inches — four inches too big, from a difference that feels imperceptible while knitting.
How to Swatch
- Cast on about 6 inches’ worth of stitches using the pattern’s suggested needles. If the gauge is 5 sts/inch, cast on around 30.
- Work 4–5 inches in the pattern’s stitch pattern.
- Bind off and block the swatch the way you’ll treat the finished item. Blocking changes gauge, sometimes considerably.
- Measure across 4 inches of the middle stitches, excluding the edges, which distort.
- Adjust needle size: too many stitches per inch means you’re knitting tight — go up a needle size. Too few means loose — go down.
Measure over 4 inches, not 1. Stitches-per-inch often comes out as a decimal, and small measurement errors multiply across a garment.
Gauge also varies with needle material — wood, metal and plastic all knit slightly differently — and between straight and circular needles. Swatch with the needles you’ll actually use.
Never rely solely on the needle size printed on the yarn label. Individual tension varies; that number is a starting point, not an instruction.
Reading a Pattern
Common abbreviations:
- k — knit, p — purl
- st / sts — stitch / stitches
- CO — cast on, BO — bind off
- k2tog — knit two together
- ssk — slip slip knit
- yo — yarn over
- rep — repeat
- RS / WS — right side / wrong side
- pm / sm — place marker / slip marker
- *…* — repeat the instructions between asterisks
Read the whole pattern before starting. Check the gauge, the finished measurements, and whether it’s worked flat or in the round.
First Projects That Work
Good first projects:
- Dishcloth or washcloth — small, fast, garter stitch, no shaping
- Simple scarf — practises consistency without shaping
- Cowl in the round — introduces circular knitting with no seaming
- Simple hat — introduces decreasing
Leave until later:
- Anything requiring precise fit
- Lace, which is unforgiving of mistakes
- Colourwork
- Socks — a genuine skill jump
Common Problems
Extra stitches appearing. Usually accidental yarn-overs, or splitting the yarn. Count stitches at the end of each row until it becomes habit.
Stitches disappearing. Dropped stitches. Catch them with a crochet hook and work them back up.
Edges are loose and untidy. Very common. Slipping the first stitch of each row tidies it considerably.
Fabric is wider at one end. Tension changed as you relaxed — normal, and it evens out with practice.
Stockinette curls badly. Structural and unavoidable. Add a garter or rib border, or block it.
Stitches are twisted. The stitch was mounted backwards on the needle. Make sure the right leg of each stitch sits at the front.
The finished item is the wrong size. Gauge. Your tension differs from the pattern’s, and the difference compounds across every stitch.
Hands ache. Gripping too tightly — the most common beginner habit. Loose, relaxed hands produce more even stitches and less fatigue.
Blocking
Blocking is wetting or steaming a finished piece and shaping it as it dries. It evens out stitches, opens up lace, and sets the final measurements.
Wet blocking — soak, gently squeeze out water (never wring), pin to shape, air dry. Steam blocking — hover a steam iron above the piece without touching it.
Check the fibre first. Superwash wool relaxes considerably when blocked; acrylic can be permanently flattened by heat.

Frequently Asked Questions
What needles and yarn should a complete beginner buy? US 7–9 (4.5–5.5mm) bamboo or wooden needles, and a DK or worsted weight yarn in a light solid colour. Bamboo grips stitches better than metal while you’re learning, and light solid yarn makes loops visible. Avoid chunky, very fine, dark or textured yarn to start.
What’s the difference between knit and purl? They’re the same action from opposite sides — a purl is the reverse of a knit. Knitting every row gives garter stitch; alternating knit and purl rows gives stockinette. A knit stitch looks like a V; a purl looks like a horizontal bump.
Do I really need to make a gauge swatch? For anything that needs to fit, yes. At 5 stitches per inch a 200-stitch cast-on gives 40 inches; at 4.5 stitches per inch the same cast-on gives 44 inches. That difference is invisible while knitting and obvious in the finished garment. Scarves and blankets are more forgiving.
How do I fix a dropped stitch? Catch the loop with a crochet hook before it runs further, then work it back up through each ladder rung until it reaches the needle. Insert it onto the needle with the right leg forward. It’s far easier than it looks.
Why does my knitting curl at the edges? If it’s stockinette, that’s structural and unavoidable — the same reason machine-knitted jersey curls. Add a garter stitch or rib border, or block the finished piece. Garter and seed stitch don’t curl.
Why is my knitting getting wider (or narrower)? Either accidental increases and decreases — count your stitches each row — or your tension changing as you relax into it. Both are normal early on and resolve with practice.
What does it mean when a pattern says “block the finished piece”? Wet or steam the piece and pin it to the correct shape while it dries. It evens out stitches, sets the measurements, and opens up lace patterns. Check your fibre first — heat can permanently flatten acrylic.
Should I learn knitting or crochet first? Either. Knitting uses two needles and holds live stitches, producing more elastic fabric that suits garments. Crochet uses one hook with a single live loop, is easier to undo and to work in three dimensions, but uses more yarn. Many people find crochet slightly faster to pick up.
