Adding stitches mid-project keeps your fabric from narrowing and lets you shape sleeves, necklines, and edges

When you need more stitches on your needle while knitting, you have several methods to choose from. The method you pick depends on where you're adding stitches, how many you need, and whether you want the new stitches to blend invisibly or create a visible edge. Most knitters use one of three techniques: yarn overs (which create a decorative hole), lifted increases (which pull stitches from the row below), or cast-on methods worked directly into the live stitches on your needle.

The most common reason to add stitches is shaping — widening a sleeve cap, expanding a body section, or creating a buttonband. You can add one stitch at a time along an edge over several rows, or add multiple stitches at once by casting on. Each approach produces a different look and requires a different technique.

Key Takeaways

  • Yarn overs are the fastest way to add a single stitch and create a decorative eyelet, but they leave a visible hole in the fabric.
  • Lifted increases (M1L and M1R) add stitches invisibly by picking up the strand between two stitches and knitting it, and work best for gradual shaping.
  • Casting on new stitches directly onto your needle adds multiple stitches at once and works well for buttonbands, sleeves, or collar sections.
  • The direction you increase (left-leaning or right-leaning) matters for symmetry, especially when adding stitches on both sides of a piece.

Yarn overs: the quickest single-stitch increase

A yarn over is the simplest way to add one stitch. You straightforward wrap the working yarn around your needle without knitting or purling. On the next row, you knit or purl that new loop as a regular stitch. Yarn overs create a small hole in your fabric, which is why they're used in lace patterns and decorative shaping.

To work a yarn over on a knit row, bring the yarn to the front of your work between the needles, then move it to the back over the top of the right needle. Knit the next stitch normally. The wrapped yarn becomes your new stitch. On a purl row, the yarn is already at the front, so you straightforward purl the next stitch and the yarn wraps automatically.

Yarn overs are fast and require no extra technique, but the hole they create is permanent. Use them when you want a decorative element — like eyelets along a sleeve edge or a lace panel — rather than invisible shaping.

Lifted increases: adding stitches that blend into the fabric

Lifted increases (also called make-one or M1 increases) pick up the horizontal strand that runs between two stitches and knit it as a new stitch. They add one stitch at a time and leave no hole. The new stitch blends into the fabric, making lifted increases the standard choice for shaping garment pieces.

To work an M1L (make-one left-leaning), insert your left needle from left to right under the strand between the stitch you just knit and the next stitch. Knit through the back loop of that strand. For an M1R (make-one right-leaning), insert your left needle from right to left under the same strand and knit through the front loop. The direction you choose determines which way the new stitch leans, which matters for symmetry when you're increasing on both sides of a piece.

Lifted increases work best when you're adding stitches gradually — one or two per row over several rows. They're invisible and professional-looking, which is why most garment patterns call for them. If your pattern doesn't specify which type, M1L on the left edge and M1R on the right edge create balanced shaping.

Casting on new stitches for multiple increases at once

When you need to add many stitches at once — for a sleeve cap, a collar, or a buttonband — you cast on directly onto your working needle. This is faster than adding stitches one at a time and creates a clean edge. The most common methods are the cable cast-on and the provisional cast-on.

For a cable cast-on, hold your needle with the live stitches in your left hand. Insert your right needle between the first and second stitch on the left needle, wrap the yarn, and pull a loop through. Place that loop on your left needle. Repeat this process for each new stitch you need. Cable cast-on creates a firm, structured edge and is visible, so use it when the edge will show or when you need durability.

A provisional cast-on uses a temporary yarn in a contrasting color. You cast on the new stitches with the temporary yarn, then later unravel it and pick up the live stitches to knit in the opposite direction. This technique is useful when you're adding stitches that will later be grafted or seamed, because it gives you live stitches to work with instead of a bound-off edge.

Where to add stitches: edges versus mid-row

You can add stitches at the edge of your work (at the beginning or end of a row) or in the middle of a row. Edge increases are most common for shaping sleeves and armholes. You work them at the start or end of a row, usually over several rows to create a gradual slope.

Mid-row increases are less common but appear in some patterns for decorative shaping or to add stitches within a panel. Yarn overs and lifted increases both work mid-row. If your pattern calls for increases in the middle of a row, it will specify the exact stitch count and placement.

When adding stitches at an edge, work the increase one or two stitches in from the edge. This creates a neater selvage and makes seaming easier later. For example, if you're increasing on a knit row, knit one stitch, then work your increase, then continue knitting. This keeps the edge stitch clean.

Matching increases on both sides for symmetrical shaping

Garment pieces often need increases on both the left and right edges to widen evenly. When you do this, use opposite-leaning increases so the shaping looks balanced. On the right edge, use M1R (right-leaning). On the left edge, use M1L (left-leaning). This creates a mirror image and looks intentional rather than accidental.

If you're adding stitches at the beginning and end of the same row, work the left-edge increase first, knit across, then work the right-edge increase. This keeps your stitch count consistent and makes it easier to track your progress. Many patterns write this as "increase 1 stitch each end of row" — meaning one increase on each side in the same row.

When you're increasing over many rows, mark your increases with stitch markers or a row counter so you don't lose track. Patterns often specify "increase 1 stitch each end every other row 10 times" — meaning you'll work increases on alternating rows, adding 20 stitches total (10 on each side).

Common mistakes and how to avoid them

The most common mistake is adding stitches too close to the edge, which creates a messy selvage. Always work at least one stitch in from the edge. Another mistake is forgetting which type of increase you used, which breaks the symmetry of your shaping. Write down the increase method your pattern calls for and stick with it throughout.

Yarn overs are sometimes worked by accident when you move your yarn between needles without intending to increase. If your stitch count climbs unexpectedly, check whether you've been creating unintended yarn overs. Similarly, if you're working lifted increases and your stitches look loose or uneven, you may be picking up the strand incorrectly. The strand should be taut, not slack.

If you add stitches but they look different from the rest of your fabric — too loose, too tight, or visibly offset — check your tension. New stitches sometimes need slightly tighter tension than the surrounding fabric. Practice on a swatch before working increases on a garment.

Frequently Asked Questions

What's the difference between M1L and M1R?

M1L (make-one left) leans to the left and is worked by inserting the needle from left to right under the strand and knitting through the back loop. M1R (make-one right) leans to the right and is worked by inserting from right to left and knitting through the front loop. Use M1L on the left edge and M1R on the right edge for balanced shaping.

Can I add stitches in the middle of a row?

Yes. Yarn overs and lifted increases both work mid-row. Your pattern will tell you exactly where to place them. Mid-row increases are less common than edge increases but appear in some decorative or textured patterns.

How many stitches can I add at once?

You can add as many as you need by casting on. Cable cast-on and provisional cast-on both work for multiple stitches. If you're adding more than five or six stitches, casting on is faster than working individual increases row by row.

What if my pattern doesn't say which increase to use?

Use lifted increases (M1L and M1R) as your default. They're invisible, professional-looking, and work for almost any shaping. If the pattern calls for a specific look — like decorative eyelets — it will specify yarn overs or another method.

Do I count new stitches toward my stitch count right away?

Yes. As soon as you add a stitch, it counts. If your pattern says you should have 50 stitches after increases, count the new stitches in that total. This helps you catch mistakes early.
