PurlbedPleats and folds › Diagonal and V folds
Diagonal-boundary chevron transfers
Large V/arrowhead shapes of knit vs purl with smooth diagonal boundaries; the fabric folds sharply along the diagonals into a structured pleat or zigzag concertina; plated, shows two-tone chevrons.
- Two beds

Drawn for: Double-bed hand flat (V-bed)Approximate preview worked out from the bed chart, not a photo.
Steps
- Establish starting bed map.
- Each row (or
- , transfer the boundary stitch per chart so each boundary steps one needle.
- Reverse step direction at the chevron point.
The full card
- What it looks like
- Large V/arrowhead shapes of knit vs purl with smooth diagonal boundaries; the fabric folds sharply along the diagonals into a structured pleat or zigzag concertina; plated, shows two-tone chevrons.
- How it behaves
- fold—both a flat crease along the chevron and a vertical concertina; holds shape.
- How it works
- The front/back boundary moves one needle per row (single-stitch transfers each row or every other row), forming diagonals that reverse at mid-repeat.
- Machines
- Double bed; single transfer tool; many small transfers.
- Parameters
- repeat width W (≈ 40), height H (≈ W), slope (1 st per 1–2 rows), mirror axis, yarn (thicker main yarn, e.g. 2 ends + 1 plating).
- Steps
- 1) Establish starting bed map. 2) Each row (or 2), transfer the boundary stitch per chart so each boundary steps one needle. 3) Reverse step direction at the chevron point.
- Charting
- 1 cell = 1 st × 1 row; grey/white triangles meeting in a horizontal V point at mid-height; bold grid every 10.
- Limits and common problems
- Less elastic than rib-based layouts; can also crease horizontally.
- Combines with
- triangle-pleat, plating.
- Pieces and assembly
- Pleat direction rotates with knitting direction (knit sideways for vertical pleats).
