Photo underlay
Trace the reference without losing the pattern.
Place a photo underneath the drawing, then zoom and pan while you trace. Mirror or rotate the whole pattern when the composition needs another direction.
The stained-glass pattern studio for iPad and Mac — coming soon
GlassPattern
Draw. Pieces number themselves. Print at exact size. GlassPattern is a native, fully offline pattern studio for iPad and Mac.
Coming soon to the App StoreStart free: draw, color, materials list, and one-page reference PDF.
Inside the studio
The pattern stays the source of truth.
Materials
Know how much glass to buy before cutting.
The materials list totals glass area per color. Numbered pieces and color assignments stay connected to the pattern instead of living in a separate tally.
Exact-size output
Print the finished size, not an approximation.
Full-size PDFs tile across A4 or US-Letter pages at true measurements. SVG exports use real-world units for plotters and cutters.
Cut warnings
Catch impossible cuts while the line is still moving.
Slivers and needle-sharp corners are flagged while drawing, before they become cuts that cannot be made cleanly.
Native on Mac
A real Mac app, not the iPad screen stretched wider.
GlassPattern runs in a window with a menu bar and keyboard shortcuts. The same universal purchase covers iPad and Mac.
