Square-Base / Star Water-bomb Tessellation
A grid of plain squares with X diagonals in the cells, giving star-like or flower-like radiating creases. The relief is strong on one face; the plain squares show clearly on the reverse.

The full card
- What it looks like
- A grid of plain squares with X diagonals in the cells, giving star-like or flower-like radiating creases. The relief is strong on one face; the plain squares show clearly on the reverse.
- How it behaves
- Very dimensional. It collapses into a tiled relief. - Several stationary vertical back-bed folds form the grid's columns. - Diagonals (on the back bed in the charted version) run between them. - Full-width front-bed horizontals close each row of cells. - The diagonal rate is the standard 1:2. - There is no simple repeat, so follow the chart row by row.
- Machines
- Needs a double bed with transfers. Very labour-intensive.
- Parameters
- Cell width (columns), cell height (rows between horizontals), rate. Making the plain cells measure square on the finished fabric improves the star effect but is not essential. 1. Set the fixed vertical folds. 2. In each cell band, run the diagonals per the chart. 3. Work the full-width horizontals at the cell boundaries. 4. Tick off each section.
- Charting
- Multiple blue verticals, blue diagonals, red horizontals.
- Limits and common problems
- Losing count of rows. Non-square cells weaken the star but do not break the fold.
- Combines with
- waterbomb-tessellation.
- Pieces and assembly
- A flat panel.
