Crochet Cable Stitch.

Use smooth, visible yarn and a hook that passes comfortably around a post. Keep two removable markers or contrasting yarn scraps, scissors and a blunt yarn needle nearby. You should already be comfortable with front and back post double crochet and half double crochet.

Chain ten. Make one US double crochet into the third chain from the hook, then one into each remaining chain. This gives eight actual double crochets. The two skipped chains are uncounted in this exercise; they do not create a ninth post.

Mark the first and last actual stitch tops. This is row one. The next rows use two ordinary half double crochets at each outside edge and four post stitches in the middle. Those shorter edge stitches frame the post work; their appearance will still depend on your loop height and yarn.

Choose the face you will look at while working row two as the cable's display face. Mark it with a yarn scrap away from the stitch tops. Front and back will otherwise refer to the face towards you while working, which changes when you turn.

For row two, chain two and turn. The chain two is uncounted. Make one half double crochet under both top loops of each of the first two actual stitches.

Work one front post double crochet around each of the next four posts. Each uses one old base position, so leave the top V above that post unused. Finish with one half double crochet in each of the last two old stitch tops.

Count eight new tops: two ordinary edges, four post stitches, two ordinary edges. Do not work again into an old top V behind a post stitch to fill what looks like a gap.

For row three, chain two and turn again. Work two half double crochets, one back post double crochet around each of the next four posts, then two half double crochets. The back-post route from this reverse view keeps the columns raised towards the display face you marked.

Stop and look at both sides. These two setup rows let you distinguish the four cable posts before any crossing changes their order. If the columns switch faces, revisit the front/back route before continuing.

A front post treble begins with two yarn overs. Together with the active loop, that gives three working loops or wraps before insertion. Pass around the designated post from the working front, behind that post, then out to the front through the neighbouring gap.

Yarn over and draw up a loop around the post: four working loops are now on the hook. Yarn over and draw through two, leaving three. Repeat, leaving two. Repeat once more, leaving one active loop. The stitch is complete.

The treble-crochet lesson helps with those three pull-through-two movements. For the cable, the insertion goes around a post instead of beneath its top loops. Draw the first loop to a workable height because the stitch also needs to travel sideways.

Do not add a third initial yarn over: that would make a different stitch. Do not shorten the crossing by substituting a front post double crochet unless a complete pattern specifies that change.

For row four, chain two and turn to the marked display face. Make one half double crochet in each of the first two edge stitches.

Name the next four old posts A, B, C and D in the order your hook would ordinarily reach them from this working edge. These are local labels for this row, not permanent names for columns on both faces.

1. Leave A and B temporarily unworked. Make a front post treble around C, then another around D. Complete each separately.
2. Bring the hook across the front of those two new stitches to reach A. Tilt the fabric so you can see the old post.
3. Make a front post treble around A, then another around B. Keep this returning pair in front of the C-and-D pair throughout the crossing.

The four cable bases were worked in the order C, D, A, B. Each old post was used once. The returning A-and-B pair crosses in front; working behind the first pair would make a different overlap.

Move directly to the two remaining old edge stitches after the whole four-post group. Make one half double crochet in each. Do not revisit the unused top Vs behind the cable, and do not treat the temporary skip of A and B as two omitted positions to fill later.

Find the two edge tops at the beginning, the four new front-post-treble tops, and the two edge tops at the end. The count is still eight. Crossing four posts rearranges four stitches; it does not increase the row.

If you count six, check whether the returning pair around A and B is missing. If you count ten, check whether you also worked into two old top Vs after making their post stitches. Trace the old bases and the new tops separately instead of counting every diagonal strand as a stitch.

Look at the overlap from the display face. You should be able to follow the returning pair across the front of the first pair. A letter-order record alone cannot prove that overlap: C, D, A, B worked with the return behind would have the same count but a different crossing.

Allow the stitches room to lean. A cable can draw the fabric inward even with the correct count. If the loop height makes it difficult to enter a post or distorts the adjacent edge, ease or remake that section rather than pulling the whole panel flat to disguise it.

For row five, chain two and turn. Make one half double crochet in each of the first two edge stitches, then one back post double crochet around each of the next four cable posts in the order you now reach them. Finish with two half double crochets.

Those middle posts are the stitches made in the crossing row. Do not reach back to the old A, B, C and D bases or attempt to restore the earlier order. The crossed structure stays in place while the new row continues from its current four tops and bodies.

Count eight again. Across five rows, the practice piece has forty completed stitch positions. The four between-row chain-two turns are uncounted, and the initial two skipped foundation chains are not extra stitch posts.

Stop after this return row. A longer cable pattern needs a defined number of straight rows, a crossing interval and an edge treatment. Repeating the crossing every time you see four posts is not the same as following that repeat.

Before securing the tails, note which face was marked, which row crossed, which old posts were worked first and whether the returning pair travelled in front or behind. These details are more useful than a general left-cable or right-cable label without its stitch definition.

The approach is mirrored when your working direction is mirrored, but the local A-to-D labels still follow the order your hook reaches the old posts. Keep the written overlap instruction with the count rather than copying an unlabelled directional arrow.

Finish the tails through the actual fabric and assess the sample after care suited to its yarn. Measure the cable fabric itself before using a complete pattern for a hat, scarf or garment. Its width and flexibility cannot be inferred from the eight-stitch count or from an ordinary flat swatch made with the same hook.
