Three-row repeat: Stitch Pattern Generator

Change row height while preserving width

This panel repeats one row of single crochet, one row of half double crochet and one row of double crochet. Nine rows give three complete height cycles. The design goal is to compare three stitch heights in a continuous eighteen-stitch rectangle without introducing shaping or changing the stitch combination within a row. It can serve as a technique reference for deciding how row structure affects a decorative panel.

Specify a repeat that belongs to rows

Select Three-row height sequence in the Stitch Pattern Generator. Set width eighteen and height nine, using US terms. The three-row period is fixed by this structure. The Basic stitches-per-repeat field is disabled and does not require eighteen to be divisible by four. Keep the exported structure identifier with the project so restoring the record cannot silently turn it into a different repeated-stitch design.

Prepare comparable materials

Use smooth DK cotton and a four-millimeter hook as a starting trial, with one yarn color throughout. Keep two edge markers, scissors, a ruler and a tapestry needle nearby. One color makes it easier to compare the stitch heights directly; the interface palette is not a yarn-change schedule. Record actual yarn composition and washing instructions. Gauge and consumed length must be measured from your sample rather than inferred from this suggested hook size.

Work the first complete cycle

Chain nineteen and work eighteen single crochets starting in the second chain from the hook. For row two, chain two and turn, then work one half double crochet into each of the eighteen old stitches. For row three, chain two and turn, then work eighteen double crochets. In this construction the turning chains never count as stitches, even when their height matches the first fabric stitch. Use the first actual stitch after turning and leave the old turning chain unworked.

Repeat the cycle without adding an edge stitch

Row four returns to single crochet with one turning chain. Rows five and six use half double and double crochet with two turning chains respectively. Repeat once more for rows seven through nine. Move the edge markers into the new first and last stitches every row. Taller stitches change the row's physical depth, but the number of old stitch tops available remains eighteen. Work both top loops unless a separate instruction explicitly changes the insertion.

Audit the chart and workload

Rows one, four and seven are single crochet; rows two, five and eight are half double crochet; rows three, six and nine are double crochet. Each family therefore contributes fifty-four stitches, giving 162 fabric stitches altogether. There are nineteen starting chains. Later turns use fourteen chains: six before half-double rows, six before double rows and two before later single-crochet rows. The chart places the foundation below the nine numbered working rows; read the arrows as the working direction changes.

Use the result responsibly

The verified output is eighteen stitches by nine rows. Measure its relaxed washed size before applying the sequence to a real panel; multiplying a single-crochet row gauge by nine would ignore six rows of different heights. If the edge flares, first check whether turning chains were counted as extra stitches. Does the sequence create a named lace fabric? It has no chain-space lace. Can the height end midway through a cycle? The tool permits that, but this case deliberately uses three complete cycles. No physical sample is claimed. Consult the terminology guide when switching the labels to UK dc, htr and tr.
