UK crochet guide. Written in British English, with UK stitch names and metric measurements.
Corner-to-corner crochet is easier to picture as a growing arrangement of small tiles. You begin with one tile, add tiles along diagonal rows and later reduce the row length to reach the opposite corner.
In the common version described here, a tile contains three UK trebles beside a chain-three section. That is the same tall stitch called double crochet in US C2C tutorials.
One chart square usually represents one tile
A chart cell is not one individual treble. Treating a ten-cell-wide chart as ten stitches would produce a very different piece. Check the chart key and construction before calculating a size or buying yarn.
Tile size depends on the yarn, hook and tension. Measure several tiles together in a sample rather than using the width of one loose tile as a precise unit.
Make the first tile
Chain six. Work a UK treble into the fourth chain from the hook and into each of the next two chains. You have three trebles beside the skipped chain-three section.
Turn and chain six to begin the next increasing row. Make another three-treble tile in the same way. Join it with a slip stitch into the chain-three space of the previous tile, then chain three and work three trebles into that space. The second diagonal row now has two tiles.
See how the next diagonal grows
On an increasing row, the new outside tile begins with a chain-six start. Subsequent tiles connect to the chain-three spaces along the previous diagonal. Follow the linked visual tutorial for the orientation of the tiles and the hook at each connection.
Count complete tiles after the row. If you made three trebles but did not join in the correct space, a correct-looking stitch total may still hide a disconnected or misplaced tile.
A four-by-four planning square
| Diagonal row | Tiles in that row |
|---|---|
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4 |
| 5 | 3 |
| 6 | 2 |
| 7 | 1 |
The total is sixteen tiles, matching a four-by-four square. This is a counting model for the common tiled construction, not a promised measurement in centimetres.
Decreasing removes the outside expansion
At a decreasing edge, you travel with slip stitches to the appropriate chain space instead of adding another outward chain-six tile. At the far end, you stop before adding the extra tile that would extend that edge. Use the demonstrated method so both edges reduce as intended.
A rectangle includes a stage where one dimension stops increasing while the other continues. That is different from decreasing both edges immediately after reaching the first desired side length.
Read the chart in the direction you are working
Diagonal rows are read in alternating directions in a turned construction. Mark the current diagonal and follow any arrows supplied by the designer. Left-handed and right-handed demonstrations may orient the fabric differently.
For a name or other directional image, confirm the chart’s reading convention before starting. Do not mirror a chart automatically without checking the intended front and the instructions.
Try one colour before managing several
A single-colour sample lets you concentrate on joins and row ends. Once that structure makes sense, try a small two-colour chart and practise keeping separate yarn supplies tidy.
Long carried strands and tight colour changes can distort the tiles. Inspect both faces and leave enough yarn for secure finishing. Plan colour quantities separately rather than assuming each colour occupies the same share of the square.
Scale from the sample
Care for the sample as the yarn label directs, then measure the tile grid and estimate consumption. Keep body tiles, joins and any border distinct in your notes. This makes a larger C2C blanket a measured project rather than a guess based on the chart’s appearance.
