diamond cross

A diamond cross is a decorative open-work pattern used in warp-knit lace production, where yarn loops form diamond shapes with cross bars running through the centre of each repeat. The pattern requires a multiple of 17 stitches plus 2 edge stitches, and completes in 35 course rows. It is typically produced on warp-knitting machines (such as Raschel or tricot variants) rather than hand-knitting needles, though the stitch structure itself can be charted for hand execution.

The diamond cross derives its name from the geometric shape formed by the yarn floats and links: the outer outline creates a diamond silhouette, while internal yarn paths cross diagonally or vertically through the middle to create the cross bar effect. The pattern is reversible or near-reversible depending on the yarn tension and machine settings, making it useful for fabrics intended to be seen from both sides.

Structure and production requirements

Achieving clean, open diamond shapes demands precise guide bar settings and consistent yarn feeding. Warp-knit machines require correct heald frame indexing to stagger yarn groups properly. The open areas of the pattern are typically created by dropping certain guide bars or executing miss loops (stitches that do not overlap with preceding courses). Denser guide bar arrangements will produce a tighter diamond with finer cross bars, while loose settings create larger holes and a more open hand.

The 17-stitch repeat is relatively compact, allowing economical layout on multi-guide-bar machines and reducing waste. The 35-row repeat cycle is long enough to fully develop the diamond and cross geometry without producing an overly bulky pattern in the finished fabric. Timing errors or yarn breaks during these 35 courses can distort the symmetry visibly.

Diamond cross lace is commonly seen in bridal wear, sheer overlays, evening wear, and technical laces where the pattern must be visible from both sides. It sits between basic openwork patterns (like simple mesh) and fully figurative laces (like jacquard-style motifs). The pattern works well with fine filament yarns, elastane blends for stretch, and novelty yarns, though thick or textured yarns may obscure the delicate cross detail.
