What picking up stitches means and when you need it
Picking up stitches means drawing new yarn loops through the edge of finished knitting so you can knit in a new direction — usually to add a border, collar, or button band without casting on separately. Instead of creating stitches from scratch, you anchor them to the existing fabric, which gives you a neater join and saves you from sewing pieces together later.
You pick up stitches most often along a vertical edge (the side of your work) or a horizontal edge (a cast-off row). The technique is the same in both cases: you're threading yarn through the edge loops and loading them onto your needle so you can knit them as if they were already there.
Common projects that use picked-up stitches include neckbands on sweaters, button bands on cardigans, edgings on blankets, and sleeves knit from the armhole down. Once the stitches are on your needle, you knit them like any other row.
Key Takeaways
- Picking up stitches means threading yarn through the edge of finished knitting and loading those loops onto your needle so you can knit in a new direction.
- On a vertical edge, pick up one stitch in each row; on a horizontal edge (cast-off row), pick up one stitch in each cast-off loop.
- Use a crochet hook to thread the yarn through the edge, then transfer the loop to your knitting needle — this is faster and more even than using the needle alone.
- Pick up stitches loosely enough that the edge doesn't pucker, and count your stitches before you start knitting to catch mistakes early.
Picking up stitches along a vertical edge
A vertical edge is the side of your knitting — the column of bumps you see when you look at the edge of a finished piece. To pick up stitches here, you work along the row ends, not the individual stitches.
Hold your finished piece with the edge you want to pick up facing you. Insert a crochet hook (one size smaller than your knitting needle works well) through the first row end, from front to back. Catch the working yarn and pull it through to create a loop on the hook. Transfer that loop to your knitting needle. Repeat along the entire edge, working one stitch per row end.
The spacing matters: if you pick up too many stitches, the edge will ruffle and pucker. If you pick up too few, it will pull inward. For most projects, picking up one stitch per row end is correct. If your gauge is very loose or very tight, you may need to skip a row end occasionally or pick up in every row end plus one extra stitch every few inches — test on a small section first.
Picking up stitches along a horizontal edge
A horizontal edge is a cast-off row or a cast-on row. This is simpler than a vertical edge because you can see each individual stitch loop clearly.
Hold the piece with the edge facing you. Insert your crochet hook under the first cast-off loop (or into the first cast-on stitch), catch the yarn, and pull through. Transfer to your needle. Work one stitch per cast-off loop or cast-on stitch across the entire edge.
Because the loops are visible and evenly spaced, you're less likely to end up with puckering or gaps. This is often the easiest edge to pick up from, especially if you're new to the technique.
Using a crochet hook versus picking up with your needle
You can pick up stitches with just your knitting needle, but a crochet hook is faster and gives more even results. The hook is smaller and more precise, and it lets you create the loop before you load it onto the needle, so you're less likely to accidentally drop stitches or create twisted loops.
If you use a crochet hook, choose one that is one or two sizes smaller than your knitting needle. Insert it through the edge, catch the yarn, pull through, then slip the loop onto your knitting needle. This two-step process (hook first, then needle) is easier to control than trying to do both at once.
If you pick up directly with your needle, insert the needle through the edge from front to back, wrap the yarn around the needle as if you were knitting, and pull through. This works, but it's straightforward to miss stitches or create uneven tension, especially along a long edge.
Counting and checking your picked-up stitches
Before you knit the first row, count the stitches on your needle and compare that number to what your pattern calls for. If you're off by more than one or two stitches, it's worth frogging (unraveling) and picking up again, because the error will compound as you knit.
Also look along the edge to make sure you haven't skipped any rows or created twisted loops. A twisted loop looks like a figure-eight on your needle; if you see one, drop it, untwist it, and reload it. Twisted stitches will create a hole or a purl bump in your knit fabric.
If your picked-up edge looks uneven — some stitches loose, some tight — you can adjust tension as you knit the first row or two. Tighten loose stitches by pulling the working yarn a little harder, and loosen tight stitches by working them more gently. The edge will even out quickly.
Picking up stitches at corners and angles
Corners are the trickiest part of picking up stitches because you're transitioning from one edge direction to another. At a corner where a vertical edge meets a horizontal edge, pick up one stitch in the corner stitch itself, then continue along the next edge as normal. This prevents a gap or hole from forming at the corner.
If you're picking up around a curved edge (like a neckline), space your stitches evenly by dividing the edge into sections and picking up the same number of stitches in each section. For example, if your neckline is 60 stitches long and you want to pick up 60 stitches, pick up 10 stitches per section if you have 6 sections. This keeps the curve smooth and prevents bunching.
Common mistakes and how to avoid them
The most common mistake is picking up too many stitches, which causes the edge to ruffle. Remember: one stitch per row end on a vertical edge, one stitch per cast-off loop on a horizontal edge. If your pattern says to pick up a different ratio, follow the pattern, but test on a swatch first if you're unsure.
Another mistake is picking up stitches too tightly. Tight picked-up stitches create a stiff, uncomfortable edge and can cause the fabric to pucker. Loosen your tension slightly — think of it as a relaxed cast-on, not a tight one.
Twisted stitches are also common, especially if you're working quickly. After you pick up each stitch, glance at it to make sure it's not twisted before you move to the next one. A twisted stitch looks like an X on the needle; an untwisted stitch looks like a U.
Frequently Asked Questions
Can I pick up stitches with a needle that is a different size than my knitting needle?
Yes. Many knitters use a smaller needle or crochet hook to pick up stitches, then switch to the correct needle size before knitting the first row. This gives you more control and creates more even stitches. You can also pick up with a larger needle if you want a looser edge, though this is less common.
What if I pick up the wrong number of stitches?
If you're off by one or two stitches, you can usually adjust by increasing or decreasing in the first row. If you're off by more, unravel the picked-up row and pick up again. It's faster to fix it now than to rip out an entire border later.
Do I pick up stitches from the front or the back of the edge?
Pick up from the front (the side facing you) so the picked-up stitches sit neatly on the surface of the fabric. If you pick up from the back, the stitches will be hidden inside the fold, which is not what you want for a visible edge like a neckband.
How do I pick up stitches if the edge is very stretchy or uneven?
Block the piece before you pick up stitches. Blocking evens out the edge and makes it easier to see where each stitch should go. If the edge is still stretchy, pick up stitches more tightly than usual, or use a smaller needle to create a tighter, more stable edge.
Can I pick up stitches from a cast-on row instead of a cast-off row?
Yes, though it's less common. Picking up from a cast-on row works the same way as picking up from a cast-off row — one stitch per cast-on loop. The cast-on loops are usually on the back of the piece, so you may need to turn the piece around to see them clearly.
