You can undo knitting by pulling the yarn to unravel stitches, either one at a time or in groups
Knitting mistakes do not have to mean starting over. You can pull out stitches and return to the point where the error happened, then knit forward again. The process is called ripping back or frogging (because you "rip it, rip it"). How far back you go depends on where the mistake is and how visible it will be in the finished piece.
The two main methods are dropping stitches one at a time with a crochet hook, which takes longer but gives you control, or pulling the working yarn to unravel multiple rows at once, which is faster but requires you to pick up stitches carefully at the end. Most knitters use both methods depending on the situation.
Key Takeaways
- Ripping back means pulling yarn to undo stitches and return to where a mistake occurred, then knitting forward again.
- For mistakes a few rows back, pull the working yarn and watch stitches unravel, then use a crochet hook to pick them back onto your needle.
- For mistakes many rows back or in the middle of a piece, drop stitches one at a time with a crochet hook to keep control and avoid laddering.
- Laddering happens when a stitch drops multiple rows; catch it when ready with a crochet hook or the hole will spread.
- Some mistakes are easier to fix in place with a crochet hook than to rip back, especially if they are only one or two stitches wide.
Ripping back multiple rows at once
If the mistake is a few rows back and affects the whole row, the fastest method is to pull the working yarn (the yarn attached to your ball) and watch the stitches unravel. First, remove your needle from the stitches. Hold the working yarn in one hand and gently pull it; the rows will come undone. Stop pulling when you reach the row just before the mistake.
Once you have pulled back, you will see a row of loose loops. Insert your needle through these loops from left to right (or right to left, depending on which direction you knit). The loops should sit on your needle in the correct orientation. If a loop is twisted, untwist it before you continue knitting. This step is where most people lose stitches, so work slowly and count your stitches before you pick up the needle and resume.
Pulling back works best when you are ripping back only a few rows. If you need to go back more than five or six rows, the yarn can tangle or the loops can slip off before you get them back on the needle. In that case, use the crochet hook method instead.
Using a crochet hook to drop stitches one at a time
For mistakes deeper in your work or when you want more control, drop stitches one at a time using a crochet hook that is slightly smaller than your knitting needle. Remove your needle from the stitches. Insert the crochet hook through the first stitch on the row where you want to stop, then gently pull the working yarn. The stitch will unravel one row at a time as you pull.
Keep the crochet hook in the stitch as you pull the yarn. When you have unraveled back to the correct row, the stitch will be sitting on your crochet hook. Move it to your knitting needle. Repeat for each stitch in that row. This method is slower than pulling the whole row, but it prevents laddering (when stitches drop multiple rows and create a hole) and gives you a chance to stop if you go too far.
If you do accidentally drop a stitch and it ladders down several rows, catch it when ready with your crochet hook. Insert the hook through the dropped stitch and pull the horizontal strand of yarn above it through the stitch. Repeat this for each rung of the ladder until the stitch is back where it belongs. The longer you wait, the harder it is to fix.
Fixing mistakes without ripping back
Not every mistake requires ripping back. If the error is only one or two stitches wide and a few rows back, you can often fix it in place using a crochet hook and the horizontal strands of yarn between rows. This method is called laddering up or picking up a stitch.
Insert your crochet hook through the dropped or misworked stitch from front to back. Catch the horizontal strand of yarn directly above it (the strand that connects the two stitches on either side). Pull that strand through the stitch on your hook. Repeat for each row until the stitch is corrected and sits at the right height. This works for twisted stitches, missed yarn overs, and single-stitch mistakes that do not affect the pattern.
For mistakes in colorwork or lace patterns, ripping back is usually safer because fixing in place can distort the pattern or create tension problems. If you are unsure whether a fix will be visible, rip back.
Preventing dropped stitches while ripping back
The biggest risk when ripping back is losing stitches to the sides of your work. Before you start pulling yarn, place stitch markers or safety pins through the stitches on either end of the row you are ripping back to. This keeps them from sliding off the needle or disappearing into the fabric.
Work in good light so you can see the stitches clearly. Pull the yarn slowly and steadily rather than yanking it, which can tangle the yarn or snap it. If the yarn tangles, stop and untangle it before continuing. Once you have unraveled back to the target row, count your stitches before you pick up the needle and resume knitting. A missing stitch now is easier to fix than discovering it three rows later.
Choosing between ripping back and fixing in place
Rip back if the mistake is in a visible spot, affects multiple stitches, is in a pattern section where tension matters, or is more than a few rows back. Ripping back takes time but produces a clean result and prevents tension problems.
Fix in place if the mistake is small (one or two stitches), only a row or two back, in a stockinette or garter stitch section where it will not show, or if ripping back would require undoing a lot of work. Fixing in place is faster but only works for certain types of mistakes.
If you have already bound off and discovered a mistake, you can still rip back by carefully unraveling from the bound-off edge. This is slower and more fiddly, but it is possible. Some knitters prefer to leave small mistakes in finished pieces rather than rip back after binding off.
What to do if you lose a stitch
If a stitch drops off your needle while you are ripping back, catch it when ready with a crochet hook before it ladders down more than one row. Insert the hook through the dropped stitch from front to back, then pull the horizontal strand above it through. Repeat for each row the stitch has dropped. Once it is back at the correct height, place it back on your needle.
If you do not notice the dropped stitch until you have already ripped back several more rows, you will have to ladder it back up to the correct row. This is tedious but fixable. The longer you wait, the more rows you will have to work through. This is why many knitters use the crochet hook method for longer rips—it prevents dropped stitches in the first place.
Frequently Asked Questions
How do I know how many rows back to rip?
Count the rows from your needle down to the row just before the mistake. You can place a stitch marker in the correct row before you start ripping, or count as you pull the yarn. Stop pulling when you reach that row, then pick up the stitches on your needle.
Can I rip back if I have already knitted several inches past the mistake?
Yes, but the further back the mistake is, the more tedious the rip. If the mistake is more than an inch or two back and affects the whole row, pulling the yarn is faster than using a crochet hook. If it is a small mistake in stockinette stitch, you might decide it is not worth fixing.
What if the yarn breaks while I am ripping back?
If the working yarn breaks, you have lost the continuous strand and will have to weave in a new one. Tie a new piece of yarn to the broken end with a square knot, then continue ripping. You will have to hide the knot later, so try to place it where it will be least visible—usually in a seam or edge.
Is there a way to rip back without losing stitches?
Using a crochet hook to drop stitches one at a time is the safest method because you keep each stitch on the hook as you go. It is slower than pulling the whole row, but you will not lose stitches to the sides of your work.
Can I rip back ribbing or cables without them getting tangled?
Ribbing and cables are trickier to rip because the stitches are more compressed. Use a crochet hook and go one stitch at a time. Work slowly and keep the stitches on the hook as you unravel. Once you reach the target row, place all stitches back on your needle and count them carefully before you resume.
