Picking up stitches creates a new row of live stitches along an existing edge, so you can knit a border, neckband, button band, or collar directly onto the piece without sewing anything. Turns a raw edge into a finished one.

The standard ratio for picking up stitches along a vertical stockinette edge is 3 stitches for every 4 rows, compensating for the difference between stitch width and row height. The motion itself is quick to learn. The tricky part is spacing: how many to pick up across a given length, and how to distribute them evenly.

Pick up vs pick up and knit

Patterns use both phrases, and they mean slightly different things, though many knitters and designers use them interchangeably.

Pick up: insert the needle under a strand at the edge, wrap yarn, pull a loop through. Stitch on the needle.

Pick up and knit: insert through the edge, wrap and pull through in a single knit motion. Creates and works the stitch simultaneously.

In practice, most knitters do “pick up and knit” regardless of what the pattern says. The result is the same. If the pattern specifies a number, that’s how many should be on your needle when you’re done.

Along a horizontal edge (cast-on or bind-off)

Simplest direction. Each stitch in the edge has a visible V. Insert the needle through the center of the V (under both legs), wrap, pull through. One stitch per stitch in the edge.

Ratio is usually 1:1. Eighty bound-off stitches, pick up 80 (or however many the pattern specifies). Sometimes the pattern asks for fewer, meaning you skip stitches at regular intervals.

Along a vertical edge (side of the fabric)

This is where spacing matters. Rows and stitches aren’t the same height. A typical stockinette gauge might be 5 stitches per inch horizontally but 7 rows per inch vertically. Picking up one stitch per row gives you more stitches per inch along the vertical edge than the horizontal, and the border puckers or flares.

The standard ratio for stockinette: 3 stitches for every 4 rows. Pick up in each of the first 3 rows, skip the 4th, repeat. Works for most gauges, but your specific numbers may need tweaking.

To figure out the exact ratio: divide row gauge by stitch gauge. If your gauge is 20 stitches and 28 rows per 4 inches, the ratio is 20/28 = 0.71. That’s roughly 7 stitches per 10 rows, or about 3 for every 4 (0.75, close enough). If you need to check your gauge first, start there.

If the pattern gives an exact pickup count, divide that by the edge length in inches for the rate. Then distribute: pick up at that rate, spacing skipped rows as evenly as you can.

Along a curved edge (necklines)

Necklines combine horizontal edges (bound-off center), vertical edges (sides), and curved or diagonal edges (shaping). Each section has a different rate.

Bound-off stitches: 1 per stitch, same as horizontal.

Vertical sides: the 3-for-4 ratio (or whatever your gauge needs).

Corners where horizontal meets diagonal: pick up 1 stitch in the corner stitch itself. This prevents the gap that’s the most common neckline pickup problem.

The pattern usually gives total stitch count for the pickup. Distribute across sections proportionally: count bound-off stitches across the front, rows along each side, allocate accordingly.

If the neckline looks wavy after the first row, too many stitches. If it pulls inward, too few. Adjusting by a few in either direction fixes most problems.

Where to insert the needle

One stitch in from the edge. Between the edge stitch and the second stitch. Cleanest result. The edge stitch forms a neat fold line and the border sits just inside rather than on top.

Through the edge stitch itself. Slightly bulkier but easier and more intuitive. Some patterns specify this.

For seamed edges, pick up between the seam stitch and the next stitch. Seam allowance hides behind the border.

Be consistent along the entire edge. Switching methods mid-edge creates visible inconsistency.

Common mistakes

Too many stitches. Border flares outward and looks wavy. Redo the pickup row with fewer. Better caught immediately than after several rows of border.

Too few stitches. Border pulls inward, creating puckers. Same fix: redo.

Uneven spacing. Stretched sections and bunched sections. Before picking up, divide the edge into equal segments (mark with pins) and pick up the same count in each.

Gaps at corners. Pick up from the very corner stitch and one stitch from each adjacent section. If a small hole persists, close it with a few stitches of yarn during finishing. The seaming guide covers closing techniques in more detail.

Twisted stitches. If the picked-up stitch sits with legs crossed, it’ll look different when knitted. Leading leg should sit in front of the needle, consistent with your knitting style.

Common questions

What size needle for picking up? Use whatever the pattern specifies for the border, often one or two sizes smaller than the body needles. Smaller needles for ribbed borders produce a snugger, neater edge.

Can you use a crochet hook? Yes. Some knitters find it easier to pull loops through tight edges with a hook and then transfer to a needle. Especially helpful when the edge is firm.

Right side facing for pickup? Usually. Pick up with the RS facing so the first border row is a WS row (purl in stockinette-based borders). This places the pickup ridge on the wrong side.

How many stitches for a button band? The pattern should say. If it doesn’t, use the stitch gauge of the border pattern times the edge length. For a 20-inch front edge in a border that knits at 5 stitches per inch, roughly 100 stitches. Adjust if it puckers or flares.
