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 of your knitting — usually along a bound-off edge, a side edge, or around a neckline. You are not unraveling anything. Instead, you are anchoring fresh stitches to the fabric you have already made, so you can knit in a new direction from there.
You pick up stitches when you want to add a border, knit a collar, create sleeves on a sweater you knitted flat, or attach a band around the edge of a blanket. It is one of the most common techniques in knitting because it lets you build pieces in stages instead of all at once.
The alternative — knitting everything in one piece from the start — is more complicated for most projects. Picking up stitches is faster and gives you more control over how the edges look.
Key Takeaways
- Picking up stitches means creating new loops along an existing knitted edge using a crochet hook or knitting needle and working yarn.
- You pick up one stitch for each row on a side edge, but one stitch for every two stitches on a bound-off edge, to keep proportions even.
- A crochet hook makes picking up faster and easier than a knitting needle, especially for beginners.
- The direction you pick up matters: always work from right to left if you are right-handed, and pick up stitches on the public-facing side of your fabric so the picked-up edge looks neat.
Picking up stitches along a bound-off edge
A bound-off edge is the finished edge at the top or bottom of your piece — the one where you cast off your stitches. Picking up along this edge is the most straightforward version because the stitches are already defined.
Hold your finished piece with the bound-off edge facing you. Insert your crochet hook (or needle) under the first stitch, one row below the bound-off edge. Catch your working yarn and pull it through to create a loop on your hook. That loop is your first picked-up stitch. Repeat across the edge, working into each stitch of the row below the bind-off.
The rule: pick up one stitch for every two stitches on the bound-off edge. If your bind-off has 40 stitches, pick up 20. This prevents bunching and keeps the proportions of your new section balanced with the old one. Once you have picked up all your stitches on the crochet hook, transfer them to your knitting needle and knit as normal.
Picking up stitches along a side edge
A side edge is the selvage — the edge created by your knitting rows running vertically. This is trickier than a bound-off edge because the stitches are not as obvious, and the spacing has to be even or your new section will pull or ripple.
Hold your piece with the side edge facing you. Working from right to left (if you are right-handed), insert your crochet hook under the horizontal strand between the first and second stitch of each row. Catch your yarn and pull through. Move down one row and repeat. You should pick up one stitch for every row, or one stitch for every two rows if your rows are very tall — test on a small section first to see which looks even.
The key is consistency. If you pick up one stitch per row for the first five rows, keep doing it for all five rows. Switching back and forth creates visible gaps. Mark your rows with stitch markers every ten stitches so you do not lose count.
Using a crochet hook versus a knitting needle
A crochet hook is faster and more forgiving than a knitting needle for picking up stitches. The hook catches yarn more easily, and you can hold more stitches on it without them sliding off. Once all stitches are on the hook, you transfer them to your knitting needle in one step.
A knitting needle works too, but you have to be more careful. Each stitch sits directly on the needle, so if you are not paying attention, a stitch can slip off the tip. This is frustrating when you are halfway through picking up 60 stitches.
If you do not own a crochet hook, a needle one or two sizes smaller than your working needle will do the job. Many knitters keep a size E crochet hook (3.5 mm) in their project bag specifically for picking up stitches.
Picking up stitches around a neckline or armhole
Necklines and armholes are curved, which means you are picking up along bound-off edges and side edges at the same time. The technique is the same — one stitch per row on the sides, one stitch per two stitches on the bound-off sections — but you have to pay attention to the corners.
At a corner where a side edge meets a bound-off edge, pick up an extra stitch in the corner stitch itself. This prevents a hole from forming. Work slowly around curves and use stitch markers to divide the neckline into quarters so you can count and space evenly.
If you are picking up for a collar or ribbing, you may need to pick up slightly fewer stitches than the math suggests, because ribbing pulls inward. Knit a gauge swatch with your picked-up stitches and the yarn you plan to use, then adjust the count if needed before committing to the full neckline.
Common mistakes and how to avoid them
The most common mistake is picking up too many stitches. This creates a wavy, bunched edge that does not lie flat. Remember the rule: one stitch per row on sides, one stitch per two stitches on bound-off edges. If you are unsure, pick up fewer stitches first — you can always pick up more, but you cannot easily remove them once you have started knitting.
Another mistake is picking up on the wrong side of the fabric. Always pick up on the public-facing side (the side people will see). If you pick up on the back, the picked-up edge will look sloppy and the stitches will not sit evenly.
Uneven spacing is also common, especially on long edges. Use stitch markers every ten stitches and count frequently. If you get to the end and realize you have picked up 45 stitches instead of 40, it is easier to fix now than after you have knitted three inches.
Fixing picked-up stitches that look loose or uneven
If your picked-up stitches look loose or sloppy, tighten the first row by knitting it firmly. The first row of picked-up stitches is always a little loose because you are anchoring new yarn to old fabric. Pulling the yarn snug as you work the first row helps.
If one section looks bunched and another looks stretched, you likely picked up unevenly. You can frog (unravel) back to the picked-up row, adjust the stitch count, and start again. This is frustrating but faster than knitting several inches only to realize the edge does not lie flat.
If the picked-up edge itself looks messy — with visible holes or loose strands — you may have picked up on the wrong side or missed the correct spot on each row. Check that you are going under the right horizontal strand, and that you are working on the public side of your fabric.
Frequently Asked Questions
Do I have to use a crochet hook, or can I use a knitting needle?
You can use a knitting needle, but a crochet hook is easier. The hook is more forgiving, and stitches are less likely to slip off. If you do not have a crochet hook, use a needle one or two sizes smaller than your working needle.
What if I pick up the wrong number of stitches?
If you realize the mistake before you have knitted more than a row or two, frog back and pick up again. If you have already knitted several rows, you can sometimes adjust by increasing or decreasing stitches in the first row of your new section, but this creates visible bumps. It is better to redo it.
Can I pick up stitches if my edge is curling?
Yes, but block your piece first if possible. A curled edge is harder to work with and the picked-up stitches may not sit evenly. If you cannot block, work slowly and use stitch markers to keep track of your spacing.
How do I pick up stitches on a ribbed edge?
Pick up in the same way as a regular edge, but pick up slightly fewer stitches than the math suggests — ribbing pulls inward, so extra stitches will create a wavy edge. Knit a small swatch first to see how much the ribbing contracts, then adjust your stitch count.
What if there is a hole where I picked up stitches?
A small hole usually means you missed a stitch or picked up in the wrong spot. You can close it by threading yarn through the hole with a tapestry needle and tightening it. For larger holes, you may need to frog back and pick up again, making sure you are going under the correct strand on each row.
