“Multiple of six plus two” is a recipe for a valid starting count. It does not mean every row will contain a multiple of six, and it does not automatically tell you to add another turning chain. The safest approach is to separate the repeating section from everything the pattern adds at its edges.
Stitch terminology: This guide uses US names. US single crochet is UK double crochet; US half double is UK half treble; US double is UK treble. See the full US/UK reference.
Write the instruction as three separate pieces
Record the repeat width, any fixed extra stitches and whether the instruction refers to the foundation chain or the finished row. If the designer gives a complete starting-chain formula, use it exactly. Adding a familiar chain-three on top can break an otherwise correct count.
| Instruction | Example valid counts | What needs checking |
|---|---|---|
| Starting chain: 6n + 2 | 20, 26, 32, 38 | The extra two are already included |
| Row: 6n stitches | 18, 24, 30, 36 | Starting chains are specified elsewhere |
| Four repeats plus two edge stitches | 26 row stitches | How the first row is established |
Choose a nearby count from your gauge
Suppose your measured fabric has 16 stitches per 10 cm, and you want a 35 cm width. The first estimate is 35 × 16 ÷ 10 = 56 stitches. If the finished row must contain 6n + 2 stitches, 56 is valid: it contains nine repeats and two extras.
If the target were 34 cm, the estimate would be 54.4 stitches. The neighbouring valid counts would be 50 and 56, giving estimated widths of 31.25 cm and 35 cm. Choose deliberately between those sizes; rounding 54.4 to 54 would not preserve the repeat.
Do not transfer a chain formula to the wrong row
A first row can skip chains, place several stitches in one chain, or count a turning chain as a stitch. That means the number of starting chains and the number of stitch tops may differ.
For a simple single-crochet strip of 24 stitches, chain 25 and work from the second chain. That familiar extra chain belongs to this particular setup. A shell or star-stitch foundation can follow a different rule entirely.
Check one repeat with the edges attached
Before scaling up, make a small sample containing at least two complete repeats and both edges. This catches a subtle problem: a repeat may be correct in the middle but require a partial group at the beginning or end.
Count how many base positions each group uses and how many positions it creates for the next row. A group of five stitches placed into one base stitch uses one base position. It does not consume five simply because it produces five new stitches.
Allow for the border after planning the body
If a finished panel should be 40 cm wide and the border adds 2 cm on each side, the body target is 36 cm. Calculate the body repeat from 36 cm, then check the border’s own requirements. Some borders need a particular number of stitches between corners.
The same method works in inches: use stitches per inch and the width in inches throughout. Avoid mixing a 10 cm gauge measurement with an inch-based target before converting.
Save the arithmetic with the project
A useful note reads “nine repeats, two edge stitches, 56 stitches after row one.” Add the actual starting chain and measured width once the sample is finished. That record is much more reliable than remembering only the number of chains.
