UK crochet guide. Written in British English, with UK stitch names and metric measurements.
Granny stripes use familiar groups of three trebles, but the two edges do not look the same on every row. One row can begin with a pair of stitches, while the next starts with a single edge stitch. That changing arrangement keeps the groups staggered.
This guide uses UK trebles, the stitch called double crochet in US instructions. Each treble starts with one yarn-over and finishes with two pull-throughs of two loops.
Work into the gaps between groups
After the foundation rows, groups usually sit in the spaces between earlier groups. They do not go into every treble top. Working three trebles into every visible stitch would increase the width dramatically.
The gaps may exist without a chain between groups. Identify the opening between the neighbouring groups rather than searching for a chain that the pattern never asked you to make.
Try a short foundation
For a small structural exercise, chain fourteen and work UK dc into the second chain and each chain across. You have thirteen dc. Turn.
Chain three, counting it as a treble, and make another treble in the same first stitch. Miss two stitches, make three trebles in the next stitch, and repeat that movement twice more. Miss the last two intervening stitches and make two trebles in the final stitch.
The grouped row has a two-stitch edge at each end and three complete three-treble groups between them. Check the spaces between those five visible groups before continuing.
The next row changes the edge arrangement
Turn and chain three as the first counted treble. Make three trebles in each of the four gaps between groups. Finish with one treble in the top of the previous turning chain.
This row has four complete groups and one edge treble at each end. For the following alternating row, use the full tutorial linked below to place the edge pairs and interior groups consistently.
| Part of the sample | What to count |
|---|---|
| Foundation dc row | 13 dc |
| First grouped row | Two edge pairs plus three full groups: 13 counted trebles |
| Next grouped row | Two single edges plus four full groups: 14 counted trebles |
A changing count can be intentional
This construction shows why counting all stitches without reading the row structure can be confusing. The two grouped rows have different totals but are designed to sit across the same strip. Use the count and edge arrangement for the particular row.
If a pattern gives another foundation convention, follow that version from the beginning. Mixing a starting count from one tutorial with the edges from another can leave a repeat short at the end.
Plan the colour changes before the blanket
Changing every row creates more ends than using wider stripes. It also means more separate colour quantities to estimate. Make a short sequence of the colours in the actual stitch, rather than deciding solely from balls lined up on a table.
Finish the last pull-through before the new colour begins using the new yarn, as directed by the chosen pattern. Secure the tails and check that any yarn carried at an edge allows the fabric to move freely.
Measure a full repeat of the fabric
Work several alternating rows before measuring. Use the same number of complete repeats when comparing samples, and keep the two edge arrangements outside the interior repeat count.
Once the sample is consistent, choose the full pattern’s foundation multiple for the intended width. A loose chain measured before any rows are added is a less useful guide than the actual cared-for granny-stripe fabric.
