Wave border: Blanket Border & Corner Generator

Use stitch heights on straight sides

This one-round finish puts six complete eight-stitch height waves around a counted rectangle. Two waves fit each sixteen-base long side, and one fits each eight-base short side. Single crochet, half double crochet, double crochet and treble crochet create the changing profile. The corners remain separate three-single-crochet turns. The goal is decorative height variation without skipping ordinary receiving bases or confusing color waves with shaped crochet increases.

Establish fifty-two insertion positions

Prepare sixteen ordinary bases on both long sides and eight on both short sides. Those forty-eight positions plus four corner bases total fifty-two. Mark every corner and the beginning of each eight-base unit. Use a smooth compatible yarn, a trial hook and a start marker. A side measured in centimeters cannot substitute for a stitch-base count. Resolve row-end pickup spacing on a sample before treating the receiving edge as ready for the generated circuit.

Work the eight distinct bases

After the initial corner, work single crochet, half double crochet, double crochet, treble crochet, treble crochet, double crochet, half double crochet and single crochet, each into its own successive old base. The two tall trebles share a height, not a source. Repeat twice on a long side and once on a short side. Work three single crochets in each separate corner base and mark the middle stitch if the finished trial will later be studied further.

Verify stitch types as well as the total

Each height repeat contains two stitches of each type. Across six repeats the sides therefore contribute twelve single crochets, twelve half double crochets, twelve double crochets and twelve trebles. Four corners add twelve more single crochets. The complete round contains twenty-four single crochets and twelve of each taller type, sixty completed stitches altogether. Every ordinary source produces one stitch; the four corner increases account for the eight-stitch expansion from fifty-two to sixty.

Finish a one-round edge

Begin with the written uncounted chain and join to the first actual stitch after the last side. This implementation supports one wave round because the resulting mixed-height edge needs a separate specification before another layer is added. Fasten off, weave ends and inspect the relaxed side profile. A counted height sequence does not determine a measured wave amplitude. Compare the sample against the receiving fabric rather than stretching it into an imagined sinusoidal outline.

FAQ and repair decisions

Why do the tall stitches bunch together?

Check that each treble uses a different old base. Working both into one position creates an unplanned increase and leaves another base unused.

Can I crochet a second identical wave round?

Not as the same validated construction. Select a separate follow-on design with explicit insertion sources for the uneven edge.

Should I add corner chains?

The supplied corner is three single crochets without a chain space. Adding chains changes the structure and should be recorded as another trial.

Exact generator inputs and full instructions

Use the wave construction, long sides 16 ordinary bases, short sides 8 ordinary bases and 1 border round. Palette: #307A86, #307A86. The resulting main counts are 60. In UK terminology US sc becomes dc, hdc becomes htr, dc becomes tr, tr becomes dtr and front/back-post dc becomes front/back-post tr. Ordinary joins and height chains stay outside the main counts.
