How to Fix Mistakes in Crochet: Frogging, Lifelines and Wrong Stitch Counts

Every crocheter makes mistakes, and the good news is that crochet is one of the easiest crafts to fix. You work with one loop at a time, so you can undo your work stitch by stitch without damaging anything. This guide shows how to unravel safely, how to find where a mistake started, how to use a lifeline and how to decide when to fix a problem and when to leave it.

Why crochet is easy to undo

In crochet only one loop is live on the hook at any time. If you pull on the working yarn, the last stitch comes undone and the loop gets bigger, but nothing else falls apart. Unlike some crafts, there are no rows of loops waiting to run down the fabric, so a dropped stitch is not a danger. Undoing crochet is called ripping back, and it is also called frogging, a joke on the sound "rip it, rip it".

How to rip back neatly

1. Take the hook out of the loop, and hold the work firmly near the last stitch.
2. Pull gently on the working yarn. The stitches come undone one at a time. Pull slowly, so the yarn does not tangle.
3. Stop when you reach the last stitch you are sure is correct. Take the last loop of that stitch, and put your hook back into it.
4. Check the loop is not twisted, tighten it so it is the same size as the stitches, and carry on.

If you need to undo many rows, you can pull the yarn straight out, one row at a time. Do not rush, and keep the hook in a safe place so that you do not lose the last loop. If the yarn becomes kinked after it has been undone, let it hang for a while, or steam it lightly if the label allows, so it relaxes before you use it again.

Find out where the mistake started

Most mistakes are changes in the stitch count. The quickest way to find the first wrong row is to count. Count the stitches in each row, starting from the top and going back, until you find the last row with the right number. In a pattern that gives the count in brackets, compare each round with the number. Rip back to the last round that matches.

Mistakes in amigurumi rounds

In a toy, you work in a continuous spiral, so a mistake in the stitch count shows as a lopsided or bumpy shape. Count the stitches at the end of every round, and use a stitch marker in the first stitch of the round. If the count is wrong, rip back to the last correct round. This is worth doing, because the early rounds shape the whole toy, and a small error will grow into a crooked head or a flat spot. A magic ring that came loose can also be redone in minutes.

Using a lifeline

A lifeline is a piece of thread or smooth yarn that you run through a row of stitches as a safety line. If you have to rip back later, the work stops at the lifeline, and you never go too far. It is helpful on projects with complicated stitch patterns or lace, where it is hard to find the right row again.

1. After a row you are sure is correct, thread a yarn needle with a smooth thread in a different color.
2. Pass the needle through the top loop of each stitch along that row, and leave a tail at each end.
3. Keep crocheting as normal.
4. If you have to rip back, undo the work down to the lifeline. Then put your hook back into the stitches the thread is holding, one at a time.

When to leave a mistake

Not every mistake needs fixing. A single uneven stitch in the middle of a blanket, a small gap in a toy that the stuffing will hide, or a color change that is a little off will not matter once the project is finished. Ask yourself: will this change the size, the shape or the strength of the piece? If not, and if you can live with it, you can leave it and move on. If it does change the size or the shape, as in a fitted hat, rip back.

How to make fewer mistakes

• Count the stitches at the end of every row or round, not only when something looks wrong.
• Use stitch markers at the start of rounds and at key points.
• Work in good light, and use light-colored, smooth yarn when you are learning.
• Tick off each row or round in the pattern, or use a row counter.
• Read the pattern through before you start, especially the abbreviations. Our guide on how to read a crochet pattern will help.
