Common Knitting and Crochet Mistakes (and How to Fix Them)
Made a mistake? How to frog knitting could help:
Most people who knit or crochet have paused at some point, looked at their work, and realised something does not look quite right. The edges might look wavy, the fabric might feel tighter than expected, or your piece might slowly be changing shape.
These small issues usually stem from a few common causes like missed stitches, shifting tension, or simple placement errors. Catching these early keeps your crafting relaxing and ensures your finished project turns out as intended.
Below are nine of the most common knitting and crochet mistakes, along with simple ways to fix them.
1. Uneven Edges
Wavy, loose, or uneven edges are common, especially for new knitters and crocheters.
Why it happens
In crochet, uneven edges usually occur when you count your turning chain as a stitch when it should be ignored, or skip it when it should be counted.
In knitting, the final stitch of a row can be accidentally dropped or become loose because it has no adjacent stitches to hold its tension.
How to fix it
- In Crochet: Place a stitch marker into the first stitch of each row so your final stitch is easy to spot when you return. Techniques like stacked stitches also create cleaner row starts.
- In Knitting: At the end of a row, bring your yarn between the needles to the front and slip the final stitch purlwise to create a neat selvedge.
2. The Project Slowly Gets Wider
Your piece gradually increases in width even though the pattern does not call for shaping.
Why it happens
In crochet, this happens when you accidentally work extra stitches into turning chains or place two stitches into the same base space.
In knitting, accidental yarn overs (bringing yarn over the needle instead of between needles when switching between knits and purls) or knitting into the legs of a stitch add extra stitches.
How to fix it
Count your stitches at the end of every few rows. If your count increases, locate the row where the extra stitch appeared and undo back to that point.
When switching between knit and purl stitches, always bring your yarn between the needle tips, never over the top.
3. The Project Gets Narrower
Your fabric gradually tapers in and becomes narrower over time.
Why it happens
In crochet, you may be skipping turning chains or missing the final edge stitch.
In knitting, working two stitches together by mistake or dropping a stitch causes the stitch count to shrink.
How to fix it
Use stitch markers in your edge stitches to keep end points visible.
Regularly inspect your knitted fabric. Knitted stitches sit in vertical columns, so any break in the column flow points to a skipped or dropped stitch.
4. Fabric That Curls
The edges of your work curl inward instead of lying flat.
Why it happens
Curling is normal when working stockinette stitch. The natural tension difference between the front knit loops and back purl loops pulls the edges inward.
In crochet, curling at the bottom edge usually means your starting chain was worked too tightly.
How to fix it
- In Knitting: Add a border in garter stitch, moss stitch, or ribbing to keep edges flat, or wet block your finished piece.
- In Crochet: Use a hook one size larger than recommended just for your starting foundation chain.
5. Tension Becoming Tighter
Your stitches gradually become tighter as you work, or your second sleeve turns out smaller than the first.
Why it happens
Tension changes with hand fatigue, posture, gripping the yarn too tightly, or concentrating hard on a tricky pattern section.
How to fix it
Take regular breaks to rest your hands and shoulders. Walk around to reset your posture and loosen your grip on the yarn.
If size differences affect your garment, checking your gauge on a swatch before starting helps spot tension shifts early.
6. Unexpected Holes in the Fabric
Small holes appear in areas where the pattern should be solid.
Why it happens
In knitting, holes stem from accidental yarn overs, dropped stitches, or splitting the yarn with your needle tip.
In crochet, holes occur if your hook passes between stitches instead of through the top loops, or if you add an extra chain by mistake.
How to fix it
Work in good lighting so you can see where your hook or needle enters.
If you drop a knitted stitch, use a crochet hook to ladder the dropped loop back up the vertical column to your live needle.
7. Yarn Splitting While Working
Your hook or needle catches individual strands, separating the yarn plies.
Why it happens
Splitting happens more often with loosely spun or multi-ply plant-based yarns like organic cotton and linen, especially when using sharp needle or hook tips.
How to fix it
Switch to a tool with a slightly blunter or smoother tip so it glides past yarn strands without catching them.
8. Twisted Stitches - Knitting
Knitted stitches look slanted or crossed, making the fabric feel stiffer than expected.
Why it happens
Twisting occurs when yarn is wrapped clockwise around the needle or when stitches are mounted backwards onto the needle.
How to fix it
Wrap your yarn anticlockwise around the needle. When entering a stitch, ensure the front leg sits to the right of the needle.
If you drop a stitch and need to place this back on the needle, ensure that this is orientated with the leg at the front leaning to the right.
This is one of the easiest mistakes to correct once you recognise it.
9. Yarn Over vs Yarn Under (Crochet)
Your crochet stitches look tighter, squarer, and denser than the pattern photos.
Why it happens
Standard crochet uses a yarn over motion (bringing yarn over the hook from back to front). Wrapping the yarn under the hook creates a yarn under stitch.
What effect it has
Yarn under creates a denser, squarer stitch. Crafters sometimes use this intentionally for amigurumi to keep stuffing hidden, but for standard patterns, it alters your gauge.
How to fix it
Check how your yarn wraps over your hook. Using a consistent yarn over motion ensures your stitches match standard pattern samples.
Simple Habits That Prevent Most Mistakes
- Count Stitches: Count your stitches at the end of rows when learning a new pattern.
- Use Stitch Markers: Mark your first and last stitches on every row.
- Take Breaks: Rest your hands to maintain steady yarn tension.
- Work in Good Lighting: Clear light helps you spot split strands and dropped loops immediately.
- Swatch First: Work a gauge swatch before starting garments or fitted items.
Final Thoughts
Small mistakes are a natural part of making. Learning to recognise why an error occurred and knowing how to fix it lets you approach every project with quiet confidence.
Frequently Asked Questions
Are small knitting and crochet mistakes normal? Yes. Every maker occasionally drops a stitch or notices a tension shift. Recognising the issue and adjusting is part of the process.
Should I fix mistakes immediately? If a mistake changes your stitch count or fabric shape, fix it straight away. Correcting an issue a few rows back is much easier than fixing it at the end.
Why does my tension change while I am working? Tension varies with hand fatigue, speed, posture, or concentrating on complex sections. Taking breaks helps keep your tension even.
Do different needles or hooks affect my stitches? Yes. Bamboo tools grip plant-based yarn slightly more, while metal needles let stitches slide freely. Use the same tools for your swatch and project.
Why does my crochet project slowly get wider? This usually happens when extra stitches are worked into turning chains or base stitches by mistake. Counting regularly prevents extra stitches.
Why does stockinette knitting curl at the edges? Stockinette naturally curls due to the structural tension difference between knit and purl loops. Adding borders or wet blocking relaxes the fabric flat.
Can mistakes affect the final size of a project? Yes. Unintended stitch additions or tension changes alter overall dimensions over many rows.
Is it always necessary to undo mistakes? Not always. If a minor visual difference does not alter stitch count or shaping, many makers choose to leave it as part of the handmade character.
