Half-Square and Quarter Stitches
Half-square and quarter-square stitches let you fill portions of a cell, giving you angled lines and detailed shapes.
Half-Square Triangles (4 types)
Half-square triangles fill half the cell diagonally:
- Half-Square (Top-Left) — Triangle covering the top-left half
- Half-Square (Top-Right) — Triangle covering the top-right half
- Half-Square (Bottom-Left) — Triangle covering the bottom-left half
- Half-Square (Bottom-Right) — Triangle covering the bottom-right half
Combining Triangles
Two complementary half-square triangles can share a single cell. For example, you can place a Top-Left triangle in one color and a Bottom-Right triangle in a different color in the same cell. This creates a diagonal split with two colors meeting along the diagonal line.
Complementary pairs are:
- Top-Left + Bottom-Right
- Top-Right + Bottom-Left
Half-Square Rectangles (4 types)
Half-square rectangles fill half the cell along a straight edge:
- Half-Square (Top) — Fills the top half
- Half-Square (Bottom) — Fills the bottom half
- Half-Square (Left) — Fills the left half
- Half-Square (Right) — Fills the right half
Like triangles, complementary pairs can share a cell:
- Top + Bottom
- Left + Right
Quarter-Square Stitches (4 types)
Quarter-square stitches fill one quadrant of the cell:
- Quarter-Square (Top-Left) — Fills the top-left quarter
- Quarter-Square (Top-Right) — Fills the top-right quarter
- Quarter-Square (Bottom-Left) — Fills the bottom-left quarter
- Quarter-Square (Bottom-Right) — Fills the bottom-right quarter
You can combine multiple quarter-squares in a single cell to create patterns with up to four colors in one cell.
Conflict Rules
When you place a stitch that overlaps with an existing stitch in the same cell, the conflicting stitch is automatically removed. Complementary types (like Top-Left and Bottom-Right triangles) can coexist, but conflicting types (like Top-Left and Top-Right triangles, which both cover the top of the cell) cannot.
The app handles these conflicts automatically — you simply place stitches and the correct behavior is applied.
