Pleats and folds › Diagonal and V folds

Mirrored V-Pleat and X-Pleat

Work a V-band (e.g. a valley diagonal, then a mountain one). Then flip it vertically, working the reverse order, mountain then valley. An X-pleat removes the rows between the two halves.

The full card

How it behaves
The X-pleat collapses in two directions and is very mobile. The mirrored V gives sculptural geometric forms.
How it works
Work a V-band (e.g. a valley diagonal, then a mountain one). Then flip it vertically, working the reverse order, mountain then valley. An X-pleat removes the rows between the two halves.
Machines
As for herringbone-fold.
Parameters
Hgap (> 0 for a mirrored V; 0 for an X), rate, P, F. 1. Work the V-band. 2. Knit Hgap rows. 3. Work the same band mirrored top-to-bottom, with the bed order reversed. 4. Repeat.
Charting
The chart is the herringbone chart reflected about a horizontal axis. Mark the axis row.
Limits and common problems
Errors at the crossing points (where two diagonals meet) are common. Tick off rows.
Combines with
x-pleat-pyramid-strip, waterbomb tessellations.
Pieces and assembly
Flat panels; pin-block them to set the facets.
