What picking up stitches means and when you need it
Picking up stitches means using your needle and yarn to create new loops along an existing edge — usually the side of your work, a cast-on edge, or a bound-off edge — so you can knit in a new direction from there. You do this when you want to add a border, knit sleeves onto a body piece, or continue a project after binding off.
The most common reason to pick up stitches is adding a neckband or ribbed edge to a finished piece. Instead of sewing a separate band on later, you pick up stitches directly from the edge and knit downward. This creates a neater finish and means fewer seams to close.
You also pick up stitches when knitting a garment in pieces — for example, after you finish the front and back panels of a sweater, you pick up stitches along the armhole edge to knit the sleeve cap down into the body. The same technique works for adding button bands, collars, or any border that needs to be perpendicular to an existing edge.
Key Takeaways
- Picking up stitches creates new loops along an existing edge so you can knit in a new direction without sewing a separate piece on later.
- The number of stitches to pick up depends on the pattern instructions, but a common rule is picking up three stitches for every four rows along a vertical edge.
- Use a needle one size smaller than your working needle to pick up stitches, then switch to the correct size once you begin knitting.
- Insert your needle from front to back under the bump of yarn just inside the edge stitch, pull yarn through, and repeat along the entire edge.
- Picking up stitches neatly takes practice — uneven tension is normal at first and will even out as you knit the first few rows of your new section.
How many stitches to pick up along each type of edge
Your pattern will tell you the exact number of stitches to pick up. If your pattern does not specify, use this rule: pick up three stitches for every four rows along a vertical edge (the side of your work). Along a horizontal edge (cast-on or bound-off), pick up one stitch in each stitch.
The three-for-four rule exists because rows are taller than stitches are wide. If you picked up one stitch per row, your new section would pull and pucker. Picking up fewer stitches spreads them out and keeps the edge flat.
Count your rows or stitches before you start. Mark the edge with stitch markers or safety pins every 10 rows or 10 stitches so you can space your pickups evenly. Uneven spacing is visible in the finished piece and is harder to fix later.
The step-by-step process for picking up stitches
Start with a needle one size smaller than the needle you will use for the new section. This prevents the picked-up stitches from being too loose. Hold the needle in your right hand and the yarn in your left (or reverse if you are left-handed).
Insert the needle from front to back under the bump of yarn just inside the edge stitch — not into the edge stitch itself, but the stitch next to it. This bump is the horizontal strand of yarn that sits between two rows. Pull your working yarn through to create a new loop on your needle. Repeat along the entire edge, moving from left to right (or right to left, depending on your pattern).
Space your pickups evenly. If you are picking up three stitches for every four rows, you will skip one row between some pickups. Mark every fourth row with a safety pin before you start so you know where to skip.
Once you have picked up all the stitches, switch to your correct working needle and begin knitting. The first row or two will look uneven — this is normal. The tension evens out as you work.
Picking up stitches along different edges
A vertical edge (the side of your knitted piece) requires the three-for-four rule because rows are taller than stitches are wide. Insert your needle under the bump between the edge stitch and the next stitch over. This creates a neat chain-like line along the edge.
A horizontal edge (cast-on or bound-off) is simpler: pick up one stitch in each stitch. Insert your needle under the loop of the stitch itself, not between stitches. This works because the height and width are already balanced.
A curved edge (like an armhole or neckline) is trickier because the curve changes angle. Pick up stitches more densely along the curved part and more sparsely along the straighter sections. Your pattern will usually tell you how many stitches to pick up in each section. If it does not, pick up extra stitches along the curve and decrease them away in the first row or two of the new section.
Common mistakes and how to avoid them
The most common mistake is picking up stitches too tightly. This happens when you pull the yarn too hard as you create each loop. Your new section will bunch and pucker. Pull the yarn gently and let the loops sit loosely on the needle until you switch to your working needle and begin knitting.
Uneven spacing is the second mistake. If you pick up stitches randomly without counting, some sections will have more stitches than others, and the edge will look wavy. Use stitch markers or safety pins to divide the edge into equal sections before you start.
Picking up stitches in the wrong place is the third mistake. Always insert your needle under the bump between the edge stitch and the next stitch, not into the edge stitch itself. If you pick up into the edge stitch, you will create a hole or a twisted loop.
If you pick up stitches and they look too loose or too tight, you can rip back and try again. This is easier than trying to fix it later. Rip back to the picked-up row, drop the stitches back onto your needle, and pick up again with better spacing or tension.
When to use a smaller needle for picking up
Use a needle one size smaller than your working needle when you pick up stitches. This prevents the picked-up stitches from being too loose and creating a gap between the old section and the new one.
Once you have picked up all the stitches and they are sitting on the smaller needle, switch to your correct working needle and knit the first row. The stitches will tighten up and look even. If you knit the first row on the smaller needle, the stitches will be too tight and hard to work with.
Some knitters skip the smaller needle and pick up directly onto the correct needle. This works if you have good tension control, but most knitters get better results with the two-needle method.
Frequently Asked Questions
What if I pick up too many or too few stitches?
If you have too many stitches, the new section will be too wide and will flare out. If you have too few, it will be too narrow and will pull. You can rip back and pick up again, or you can decrease or increase stitches in the first row or two to adjust. Your pattern may include instructions for this.
Can I pick up stitches with a crochet hook instead of a needle?
Yes. Many knitters use a crochet hook to pick up stitches because it is easier to insert into tight spaces and the hook catches the yarn more reliably. Once you have picked up all the stitches on the hook, transfer them to your knitting needle and continue as normal.
Do I have to pick up stitches, or can I sew a band on instead?
You can sew a band on, but picking up stitches creates a neater, flatter finish with fewer seams. Sewn bands can look bulky and are more visible from the inside. Picking up stitches is the standard method in most patterns for this reason.
Why does the edge look wavy after I pick up stitches?
A wavy edge usually means uneven spacing or uneven tension. If some stitches are picked up closer together than others, that section will bunch. If your tension is too tight in some spots and too loose in others, the edge will ripple. Mark the edge into equal sections before picking up, and try to keep your tension consistent.
What yarn should I use to pick up stitches?
Use the same yarn you are using for the new section. If you are picking up stitches to knit a neckband, use the yarn you will knit the band with. Do not use a contrasting yarn or a temporary yarn — it will show in the finished piece.
