Shape Editor

The Shape Editor is where you draw custom shapes for your blocks. You place vertices on a snap grid, connect them into a polygon, and optionally add curves to any edge. Every shape you create is guaranteed to produce clean, sewable templates.

The snap grid

Shapes are drawn on a square canvas divided into a 6 by 6 interior grid, giving you 49 snap points (7 rows and 7 columns, including the edges). Every vertex you place snaps to one of these points. There's no freeform drawing; the grid ensures that shapes are precise and repeatable.

The grid keeps shapes compatible with traditional quilting geometry. Most classic block shapes (half-square triangles, flying geese, diamonds) can be drawn on this grid.

Drawing a shape

Tap grid points to place vertices. Each vertex connects to the previous one to form an edge. When you close the shape by tapping the starting vertex (or tapping the close button), you have a complete polygon.

• Tap an empty grid point to add a vertex
• Drag an existing vertex to move it to a different grid point
• Tap an existing vertex to select it, then tap delete to remove it

Adding curves

Any straight edge can become a curve. Select an edge and use the curvature control to bend it. Curvature is quantized into discrete steps (from -6 to +6), so curves are consistent and reproducible. Negative values curve inward, positive values curve outward, and zero is a straight line.

Curved edges are fully supported in templates and yardage calculations. The curve data travels with the shape everywhere it's used.

Editing an existing shape

To modify a custom shape you've already created, long-press it in Shape Studio and choose Edit. The shape opens in the editor with all its vertices and curves intact. Make your changes and save.
