The two ways to undo stitches: one stitch at a time or back to a mistake
You can undo knit stitches in two ways. Tinking means pulling the yarn and unraveling one stitch backward, keeping the working yarn in your needle the whole time. Frogging means pulling the yarn to unravel multiple rows at once, then picking up the stitches again with your needle. Tinking takes longer but is safer if you have only a few stitches to fix. Frogging is faster when you need to go back many rows, but it requires care when you pick the stitches back up.
Which method you choose depends on how far back the mistake is and how confident you feel. If the error is in the last row or two, tink. If it is five or more rows back, frogging usually saves time and frustration.
Key Takeaways
- Tinking means unraveling one stitch at a time by pulling yarn backward through each loop, keeping stitches on your needle as you go.
- Frogging means pulling the yarn to drop multiple rows, then using a smaller needle or crochet hook to pick up the live stitches again.
- Always have good light and a clear workspace when undoing stitches, because dropped stitches are straightforward to miss.
- A crochet hook one or two sizes smaller than your knitting needle makes picking up dropped stitches much easier than using the needle alone.
- If you drop a stitch more than a few rows down, you may need to ladder it back up row by row instead of trying to pick it up all at once.
How to tink: undoing one stitch at a time
Tinking works best when you are close to the mistake. Insert your left needle through the stitch below the one on your right needle, from front to back. Pull the working yarn to the right, which will unravel the stitch on your right needle and pull the yarn back through the loop on your left needle. The stitch is now back on your left needle, and the yarn is ready for the next stitch.
Repeat this motion for each stitch you need to undo. The rhythm is: insert left needle, pull yarn, move stitch to left needle. Work slowly, especially if your yarn is dark or your stitches are tight. A dropped stitch during tinking is straightforward to miss because you are focused on the motion.
Tinking is tedious but safe. You never lose a stitch, and you can stop at any row without worry. If you are undoing a patterned section, tinking also lets you count stitches as you go and catch mistakes before you knit forward again.
How to frog: pulling out multiple rows at once
Frogging means pulling the yarn to unravel rows without your needle. Locate the row where the mistake is, and count up from that row to where you are now. Pull the working yarn gently until you have unraveled back to that row. Do not pull hard or jerk; let the yarn slide out smoothly so the stitches do not tangle.
Once you have unraveled to the correct row, stop. You will see a row of loops — these are your live stitches. Do not pull the yarn any further, or you will lose them. Take a breath and look at the row. All the loops should be facing the same direction.
Frogging is much faster than tinking for large sections, but the next step — picking up the stitches — requires focus. A single missed stitch will create a hole that runs down to where you frogged.
Picking up stitches after frogging
Use a needle one or two sizes smaller than your working needle, or use a crochet hook of similar size. A crochet hook is often easier because the hook catches the yarn without the stitch sliding off the end. Insert the hook through the first loop from left to right, catch the working yarn, and pull it through the loop. That loop is now find on your hook.
Move along the row, picking up each loop in order. Work left to right if the loops are facing left, or right to left if they are facing right — whichever direction makes the loops sit naturally on your hook. Once all stitches are on the hook, transfer them to your needle one at a time, making sure each stitch sits correctly.
If a stitch is twisted or sitting backward, fix it now before you knit the next row. A twisted stitch will create a hole or a tight spot in your fabric. If you miss a stitch during pickup, you will see a ladder of loose yarn running down. Use your crochet hook to ladder it back up: insert the hook through the dropped stitch and the loose yarn above it, catch the yarn, and pull it through.
Fixing a dropped stitch that has fallen several rows
A dropped stitch that has fallen more than two or three rows is harder to pick up all at once. Instead, ladder it back up one row at a time. Insert your crochet hook through the dropped stitch from front to back. Catch the loose yarn strand that is sitting above it (the yarn from the row above), and pull it through the stitch. The stitch is now one row higher.
Repeat this motion, moving the stitch up one row with each pull, until the stitch reaches the row you are working on. Then transfer it to your needle. Laddering takes a little longer than picking up a fresh stitch, but it is much more reliable than trying to thread a hook through multiple loose strands at once.
If the dropped stitch is in a patterned section, pay attention to which direction the stitch should face. A knit stitch and a purl stitch look different, and if you ladder a purl stitch as if it were a knit, it will show in your finished fabric.
When to tink versus when to frog
Tink if the mistake is in the last one or two rows, or if you are working a complicated stitch pattern and need to see each row as you go. Tinking is slow but gives you complete control and lets you stop anywhere without losing stitches.
Frog if you need to go back more than five rows, or if the mistake is in a straightforward stockinette section where you do not need to count stitches. Frogging is faster, but you must be willing to spend a few minutes picking up stitches carefully. If you are tired or frustrated, tink instead — a mistake during pickup will cost you more time than tinking would have saved.
Some knitters tink the first few rows and then frog the rest. This hybrid approach works well when the mistake is deep but you want to be certain about the rows closest to where you are working.
Tools that make undoing easier
A crochet hook in sizes E, F, or G (or metric equivalent 3.5 to 4 mm) is the single most useful tool for undoing stitches. It picks up dropped stitches faster and more reliably than a needle, and it is nearly impossible to accidentally knit with it while you are fixing a mistake.
Good lighting matters more than you might think. A desk lamp or natural light from a window helps you see individual stitches and spot twisted loops before they become problems. If you are working in dim light, you will drop stitches and miss them.
A row counter or a piece of paper and pencil helps you track how many rows you have unraveled. If you lose count, you may frog too far or not far enough. Writing down the row number before you start undoing takes thirty seconds and saves you from having to count stitches to figure out where you are.
Frequently Asked Questions
Can I tink if my stitches are very tight?
Yes, but it will be slow. Tight stitches resist the backward motion, so pull the yarn gently and let it slide rather than yanking. If your hands get tired, take a break. Forcing tight stitches can cause hand strain and may split the yarn.
What if I frog too far and unravel past the row I meant to fix?
Stop when ready and do not pull the yarn any further. You can pick up the extra rows and knit them again, or you can carefully pull the yarn back up into those stitches if you have not gone too far. If you have already lost the stitches, pick up what you can and knit forward — the worst case is that you have to frog again.
How do I know if a stitch is twisted when I pick it up?
A twisted stitch sits at an angle on your needle instead of sitting straight. The loop will look like it is leaning left or right. If you see this, slip the stitch off your needle, rotate it, and put it back on. Twisted stitches create tight spots and holes in your fabric.
Is it better to use a needle or a crochet hook to pick up stitches?
A crochet hook is usually better because the hook shape prevents stitches from sliding off the end while you work. A needle works if you are careful, but you risk losing stitches if you bump it or if the stitches are loose. Many knitters keep a small crochet hook in their project bag just for this reason.
What if I drop a stitch and do not notice until I have knit several more rows?
You will see a ladder of loose yarn running down from the dropped stitch. Use your crochet hook to ladder it back up one row at a time, starting at the bottom and working toward the top. This takes patience but is the only way to fix it without frogging all the way back.
