How to fix common crochet mistakes
Use the fabric, stitch count and insertion point to find the first wrong step. Undo only as far as you need to.

Count the top Vs, excluding any uncounted turning chain. A widening sc strip often has two stitches in the first or last stitch, or a stitch worked into an uncounted turning chain. A narrowing strip often misses the first stitch or the final edge stitch.
Find the last row with the intended total, undo to that row, and mark its first and last counted stitches. Work into each once. For our sc strip, chain 1 does not count; for our dc strip, chain 3 counts and the last stitch goes into the previous turning chain. Apply the rule for the actual pattern, not one rule to every stitch.
The total is wrong halfway through a repeat
Separate old stitches used from new stitches made. An increase uses one old stitch twice; sc2tog consumes two old stitches to make one. A chain space can count as a space without being a worked stitch.
Stop at the last complete repeat, mark it and recount that section against the pattern. Undo only the incomplete or incorrect group and work it again. Break long rows into marked repeat groups so an error does not hide until the final stitch.
A stitch catches or splits the yarn
Look for loose filaments left outside a loop, or a hook passing through the yarn itself instead of under a whole strand. Stop before tightening the damaged stitch.
Undo it, smooth the strand and insert beneath complete loops. Keep the active loop on the hook shaft rather than squeezing it down onto the narrow throat. If the yarn has been damaged, remove that length and join sound yarn with secure ends; do not hide a fraying strand in the next row.
The foundation pulls tighter than the rows
A tight chain can make the starting edge bow even when the stitch count is correct. Compare the relaxed chain edge with the row above it; do not force the cloth flat while measuring.
Try the foundation again with a looser, even tension. A slightly larger hook for the foundation alone can help; return to the project hook for Row 1 and check the fabric. Avoid making a huge loop followed by a tight one. Rework a short sample before restarting a long foundation.
A joined chain has a twist
Follow the chain Vs all the way around before the joining slip stitch. If one part rotates around the chain, the foundation may form a twisted band rather than a flat ring.
For the short chain ring, undo the joining slip stitch, lay the chain flat and rejoin the first chain. If later rounds are already attached to a twisted long foundation, they usually need to be undone to correct that foundation. Do not try to hide a full twist by tugging the working yarn.
Unexpected ridges or gaps appear
Find the two strands making the top V. Working through only the front or back loop creates a different texture from working under both. Working between posts creates gaps. Both can be intentional, but they are wrong when the pattern asks for ordinary stitches into both loops.
Inspect the first stitch where the texture changes. Undo to it and work under the intended loops. At a decrease, keep the two adjacent insertion points distinct. Do not use a gap between them as a shortcut.
A circle cups, ruffles or grows at the join
Count each round from its first marked stitch. Too few increases can form a cup; too many can ruffle. A steady extra stitch at the seam often means the joining slip stitch or starting chain has been counted and worked into by mistake.
Correct counts and placement first. If they match, compare tension and stitch height with the intended fabric and try a fresh small sample. A six-increase sc exercise does not establish the right count for taller stitches. Keep the same working face and round style until the pattern tells you to turn or change.
Correct counts produce the wrong size
Measure a washed, dried swatch over the pattern’s stated span. More stitches per 10 cm means smaller stitches and therefore a narrower item at the same stitch count. Fewer stitches means larger stitches. Row gauge affects height separately.
Re-swatch with an adjusted hook or tension. A plain rectangle can use measured length, but a shaped garment may place decreases or armholes by row. Do not change its row count without checking the shaping instructions.
Undo safely and restart from a known stitch
Take the hook out and gently pull the working strand, releasing one stitch at a time. Stop just before the last correct stitch would come undone, then put the hook back into the remaining active loop. Check that the working yarn leads to the ball and that the loop slides on the shaft.
Count the remaining stitches and identify the next insertion point before restarting. Fuzzy or fragile yarn can lock together; ease the snag with your fingers rather than yanking. If you must set the work down, put a removable marker through the active loop so it cannot unravel.
