Wave edge: Crochet Lace Edging Generator

Make the wave with height rather than expansion

This wave edge uses single, half double, double and treble crochet in a repeated rise-and-fall sequence. Every old base receives exactly one new stitch. The independent design question is whether the height schedule can be followed without treating its two tallest stitches as an increase. Three repeats decorate twenty-four existing bases. The drawing identifies stitch types and sources; it does not promise a measured wave amplitude or certify the outline of a physical sample.

Prepare a straight receiving strip

Choose smooth DK cotton and begin with a four-millimeter hook for a separate trial. Have scissors, a tapestry needle, three repeat markers and a ruler ready. Prepare twenty-four countable edge positions. One practice method is to chain twenty-five and work twenty-four single crochets from the second chain, then keep that receiving strip separate from the decorative-row budget. When working on another fabric, check that the marked positions are actual usable bases rather than arbitrary evenly spaced points in its side edge.

Set the eight-base height option

Select Stitch-height wave, twenty-four base edge stitches and US terms. Repeat blue #243BCE in both palette slots. Mark the beginning of each group of eight bases. The same yarn throughout keeps the task focused on stitch height. A different palette cannot repair a misplaced treble or establish matching physical tension between stitches. Keep the chosen yarn, hook and care method with any observations made from the actual trial.

1. Work on an existing 24-stitch edge. Ch1 (not counted). Repeat [sc, hdc, dc, tr, tr, dc, hdc, sc], one stitch in each successive old base,3 times. 24 completed stitches, no skipped bases or increases. Fasten off and weave in. Main count: 24.

Follow all eight separate sources

After an uncounted starting chain one, work single crochet, half double crochet, double crochet, treble crochet, treble crochet, double crochet, half double crochet and single crochet. Each operation goes into the next old base. Repeat this sequence three times. The two neighboring treble crochets occupy two different bases. Do not place both in one source, which would create an increase and leave another old position unused. Likewise, the two low single crochets at repeat boundaries remain separate stitches.

Count each height category

One repeat contains two stitches of each height. Three repeats therefore produce six single crochets, six half double crochets, six double crochets and six treble crochets. The total is twenty-four completed stitches consuming twenty-four distinct old bases. There are no intentional skips, increases, decorative chain arches or fan groups. Starting-height chains are excluded. The source map's individual lines make a doubled source distinguishable from two correctly adjacent high stitches.

Inspect height transitions before finishing

Check the first completed rise and fall before working the other two. If a peak seems off-center, read the whole eight-stitch sequence rather than moving a marker to hide the error. If the low stitches pull the receiving strip inward, verify that they occupy their own bases and compare tension in a physical sample. A correct sequence establishes operations, not an exact relaxed silhouette. Fasten off and weave the ends without stretching the final low point.

Questions before adapting the wave

Can another height repeat be substituted while keeping this artifact? A changed sequence needs its own saved input and count plan. Does the wave use fewer bases at a valley? Every position is still used once. In UK terminology, the corresponding names are dc, htr, tr and dtr, with the same sources and quantities. Consult the terminology guide when switching systems. No physical edge sample, measured wave height or finished application performance is claimed.
