Crochive · Pattern-check examples

What can a pattern check tell you?

Try five short examples in Pattern Doctor. The notes below explain what to look for; run the check to see its current report. These are authored software examples, not independently crocheted patterns.

What these checks prove

These examples test whether Crochive catches known count errors and stops when instructions are outside its supported scope.

Count checks: expected arithmetic and known errors.

Safe limits: unsupported instructions need a manual check.

A passing count check does not confirm assembly, finished shape, fit or fabric. Those still need the complete pattern and a real swatch.

Crochet terms and reading conventions — Craft Yarn Council

1 · The count that lies — and which number to fix

Round 2's stitches make 12, but the line says 11. Round 3's written repeat also fits 12 stitches below. This supports changing the stated total; review the intended design before applying a correction.

Rnd 1: 6 sc in a magic ring. (6)
Rnd 2: 2 sc in each st around. (11)
Rnd 3: (sc in next st, 2 sc in next st) around. (18)
What to look for
PASS · R1 6 sts, as declared.
FAIL · R2 the stitches on this line make 12, but it declares 11.
Suggested correction: declare 12.Twelve fits both the written increase and the following round. Confirm that those are the stitches you intended before changing the total.

2 · The round that cannot be worked at all

Every stitch needs somewhere to go. Round 2 asks for seven anchors on a round that left six. No amount of tension fixes this; the pattern is unworkable as written.

Rnd 1: 6 sc in a magic ring. (6)
Rnd 2: sc in next 7 sts. (7)
What to look for
PASS · R1 6 sts, as declared.
FAIL · R2 it needs 7 anchors, but the round below leaves 6.Every stitch needs somewhere to go. This round asks for more places than the round below provides, so it cannot be worked as written.

3 · Matching counts, possible ruffling

Round 3 makes the 36 stitches it declares, but adds 24 in one round. If the goal is a flat single-crochet circle, that is a reason to review the shaping. A deliberate frill could be correct. Yarn, tension and a swatch decide the physical result.

Rnd 1: 6 sc in a magic ring. (6)
Rnd 2: 2 sc in each st around. (12)
Rnd 3: 3 sc in each st around. (36)
What to look for
PASS · R1 6 sts, as declared.
PASS · R2 12 sts, as declared.
REVIEW SHAPE · R3 adds 24 stitches. This is a possible ruffling problem if the intended piece is flat.This is a shape heuristic, not a measurement or a guarantee about the finished fabric.

4 · A possible cupping problem

This piece doubles, holds steady, then adds only two stitches. If a flat coaster is intended, review that change in growth. It could be intentional for a bowl or another shaped project. Software cannot infer the designer's goal or predict an exact fabric angle from these counts.

Rnd 1: 6 sc in a magic ring. (6)
Rnd 2: 2 sc in each st around. (12)
Rnd 3: sc in each st around. (12)
Rnd 4: (sc in next 5 sts, 2 sc in next st) around. (14)
What to look for
PASS · R1 6 sts, as declared.
PASS · R2 12 sts, as declared.
PASS · R3 12 sts, as declared.
REVIEW SHAPE · R4 adds only two stitches. Check whether this growth matches the intended shape; a real swatch is needed.

5 · What it refuses to judge — on purpose

"Place one sc evenly around" is worked by eye; there is no exact total to compute, and a confident number here would be an invented one. The checker says what it read and stops. An honest refusal is part of the proof: a tool that never says "we cannot check this" is guessing somewhere.

With off white, ch 12
Row 1: 1 sc in the 2nd ch from the hook and in each ch across. (11 sc) Ch 1, turn.
Round 2: place one sc evenly around the entire blanket. Place 3 sc in each corner. (40)
What to look for
PASS · R1 11 sts, as declared.
MANUAL CHECK · R2 this edging is placed by eye ("evenly around"), so there is no exact total to compute from this text; its stated 40 is not independently checked.
Why this mattersThe checker only claims what it can stand behind. Where a pattern is worked by eye, counted in blocks, or written in a notation it cannot read, it says so instead of inventing a verdict.
