Frogging means pulling out stitches to undo rows of knitting
Frogging is the process of ripping out stitches in your knitting to go back and fix a mistake or start over. The name comes from the sound "rip it, rip it" — which sounds like a frog croaking. You pull the working yarn to unravel rows, then pick up the live stitches on your needle again so you can knit forward correctly.
Most knitters frog at some point. A dropped stitch, a twisted stitch several rows back, or a pattern error that you do not notice until you are halfway through a sleeve — these are all reasons to frog rather than live with the mistake or start the whole project over.
The process takes patience but is straightforward once you know the steps. The key is stopping before you unravel too far, then carefully picking up the stitches so they sit the right way on your needle.
Key Takeaways
- Frogging means pulling yarn to unravel rows of knitting back to the point where the mistake happened.
- You can frog by pulling the working yarn and letting stitches slip off the needle, or by carefully unraveling one stitch at a time with a crochet hook.
- Stop unraveling one row above the mistake, then use a crochet hook or spare needle to pick up the live stitches before you knit forward again.
- A crochet hook smaller than your knitting needle makes picking up stitches easier and faster than using your needle alone.
- If you frog more than a few rows, mark your place with a stitch marker or scrap yarn so you know exactly where to stop.
Pull the yarn to unravel rows quickly
The fastest way to frog is to pull the working yarn — the yarn attached to your ball — and let the stitches slip off your needle. Hold the needle in one hand and gently pull the yarn with the other. The stitches will unravel in a line.
Pull slowly and watch the stitches come undone. You will see the V-shape of each stitch flatten as the yarn slides through. Keep pulling until you reach the row just above the mistake. This method works well when you need to frog several rows at once.
The downside is that you lose control if you pull too hard or too fast. If you yank the yarn, you may unravel past the row you meant to stop at, and then you have to frog even further. Go slowly, especially near the end.
Use a crochet hook to frog one stitch at a time
For more control, use a crochet hook one or two sizes smaller than your knitting needle. Insert the hook through the stitch below the one on your needle, then pull the working yarn through. The stitch comes undone and the yarn below it catches on your hook.
Work from left to right across the row. Each time you pull the yarn through, you pick up the stitch below. Once you have gone across the entire row, all the stitches for that row sit on your crochet hook. Repeat for as many rows as you need to frog.
This method is slower than pulling the yarn, but you have complete control over where you stop. You can frog one stitch at a time if you want, or one row at a time. It is the safest choice when you are frogging only one or two rows.
Pick up live stitches before you knit forward
Once you have unraveled back to the row above the mistake, you need to pick up the live stitches — the loops of yarn that are now loose — and put them back on your needle. If you used a crochet hook to frog, the stitches are already on the hook. If you pulled the yarn, the stitches are loose and you need to catch them.
Use a crochet hook to pick up loose stitches. Insert the hook under the loop from left to right, catch the working yarn, and pull it through. Do this for every stitch in the row. Once all stitches are on the hook, transfer them to your knitting needle.
Make sure each stitch sits on the needle the same way — the working yarn should come from the right side of the needle, and each stitch should have the same orientation. If a stitch is twisted, slip it off and put it back the right way before you start knitting.
Mark your stopping point with a stitch marker
If you are frogging more than three or four rows, place a stitch marker in the row where you want to stop. Slip the marker onto your needle in the stitch where the mistake ends. This gives you a visual target so you do not frog too far by accident.
You can use a commercial stitch marker, a safety pin, or a loop of scrap yarn. The marker should be loose enough that you can see it clearly but tight enough that it does not slip off while you are unraveling.
When you reach the marker, stop frogging. Remove the marker and pick up the stitches on that row. This method takes a few extra seconds but saves you from having to frog twice.
Avoid frogging by catching mistakes early
The best time to frog is right after you notice the mistake, before you knit many more rows. A mistake one row back takes seconds to fix. A mistake ten rows back takes much longer.
Check your work every few rows, especially if you are learning a new stitch or pattern. Look at the stitches on your needle and compare them to the rows below. If you see a stitch that looks different — twisted, dropped, or in the wrong place — stop and frog back to fix it.
Some knitters use a lifeline: a piece of yarn threaded through a row of stitches before they start a tricky section. If something goes wrong, they frog back to the lifeline instead of all the way to the beginning. This is useful for complex patterns or when you are trying a new technique.
What to do if you frog too far
If you unravel past the row you meant to stop at, do not panic. You can frog back up by re-knitting the rows you just undid. This is called tinking — knitting spelled backwards.
To tink, insert your needle into the stitch below the one on your needle, going from right to left. Pull the working yarn to undo the stitch, then slip the stitch off your needle. The stitch below now sits on your needle. Repeat for each stitch you need to redo.
Tinking is slow but gives you complete control. You can redo one stitch at a time and stop exactly where you want. If you frogged too far by only one or two rows, tinking is often faster than frogging further and picking up stitches again.
Frequently Asked Questions
Can I frog if I have already cast off?
Yes, but it is harder. You will need to unravel the cast-off edge, then frog the rows below. Use a crochet hook to pick up stitches as you go, because loose stitches are straightforward to lose once the cast-off is gone. If you only need to fix the last row or two, tinking may be faster.
What if I drop a stitch while frogging?
A dropped stitch during frogging is just a loose loop of yarn. Use a crochet hook to pick it up and put it back on your needle in the correct row. If you do not notice until you have frogged several more rows, you may need to frog back to that stitch and pick it up before you continue.
Do I need a crochet hook to frog?
No, but it makes the job much easier. You can pick up stitches with your knitting needle, but a crochet hook is smaller and more precise. A hook one or two sizes smaller than your needle works best. If you do not have a crochet hook, a spare needle or even a toothpick can work in a pinch.
How do I know if I frogged the right number of rows?
Count the rows on your needle and compare them to the pattern or to the rows below. If you are fixing a specific stitch, make sure that stitch is gone and the row above it is on your needle. If you are unsure, frog one fewer row than you think you need — you can always frog more, but you cannot un-frog.
