Your stitch count doesn’t match. The size of the gap says whose fault it is.
Before you frog anything: subtract. What you have, minus what the round asks for. That one number narrows it to three causes, and only one of them is yours.
Read the gap
- Off by exactly the repeat count — usually 6, sometimes 8 or 12.
- You worked an increase round as plain single crochet, or a decrease round as plain single crochet, or you skipped one whole repeat group. Six increases missed means exactly six stitches missing. This is the most common one and it is yours. Rip back to the start of that round only.
- Off by one or two.
- Almost always the join. In a spiral you have worked past your marker or short of it; in joined rounds you have worked into the chain or into the slip stitch. Find your marker, count back one round, and the extra or the missing stitch is sitting right there next to it.
- Off by a number that matches nothing, or growing round after round.
- Now suspect the pattern. Check its own arithmetic before you touch the piece again — the method is below, and it takes two minutes.
Check the pattern against itself
Every round makes two separate claims: the instruction, and the number in brackets. You can test one against the other with arithmetic alone, no yarn involved.
Round 8: (sc 2, inc) x6 (24)
One repeat is sc, sc, inc. It consumes three stitches from the round below and produces four. Six repeats consume 18 and produce 24. So round 8 is only correct if round 7 ended on 18. If round 7 ended on 24, the pattern is asking you to consume stitches that are not there, and it will be wrong for every maker who buys it, not just you.
Do that for each round in turn — carry the ending count forward as the next round’s starting count. Where the carry stops matching the brackets is where the pattern breaks. That is the whole method, and it is why a row-counter app can never tell you this: it counts your clicks, it has never read the pattern.
Or have every round checked for you
Paste the written pattern you own. Sunny Rope writes out every repeat, carries the count from round to round, and names the round where the numbers stop closing — in a sentence you can send to whoever sold it to you. Free, no account, and the pattern never leaves your browser.

If the count matches and the shape still doesn’t
Increases in the wrong place still add up. Six increases over 30 stitches belong about five stitches apart; stacked in one column they make a ridge and a lopsided head, while the total stays perfectly correct. If a pattern wants them stacked, it says so. If it doesn’t say, spread them.
