GlassPattern: Stained Glass

Draw stained glass patterns on iPad and Mac. Pieces number themselves, slivers get flagged, and your pattern prints at exact size. One-time purchase. No subscription.

GlassPattern is a stained glass pattern studio built for the way glass artists actually work — on iPad with Apple Pencil, and on Mac as a real Mac app. Draw your design; every closed shape becomes a numbered piece automatically. When you're ready to cut, print your pattern at exact finished size.

DRAW LIKE ON PAPER, GET A REAL PATTERN • Sketch freehand — closed shapes become numbered pieces automatically • Slivers and razor-sharp corners are flagged as you draw, before they ruin a cut • Import a photo and trace over it to turn any image into a pattern • Zoom and pan smoothly around large designs • Mirror and rotate your whole pattern • Came and copper-foil line styles

PLAN YOUR GLASS • Assign a glass color to every piece • The materials list totals the area of each glass you'll need — know what to buy before you cut • Piece count and finished size always in view

PRINT AT EXACT SIZE • Export a full-size pattern that tiles across standard pages — tape together and cut, measurements true to the millimeter • Export SVG in real-world units for plotters and cutters • One-page reference sheet with the numbered layout

MADE FOR THE WORKBENCH • Works completely offline — no account, no cloud, no sign-up • Your designs never leave your device; we collect nothing • iPad and Mac with one purchase • In English, Spanish, German, French, Italian, Dutch, Portuguese, and Japanese • Metric and imperial, true to your region — type 12.7 or 12,7, both just work

FREE TO REALLY TRY Drawing, coloring, the materials list, and the one-page reference PDF are free — design a full piece before spending anything. A single one-time purchase unlocks full-size printing and SVG export. No subscription. Ever.

Whether it's your first suncatcher or a commissioned church panel, GlassPattern takes you from idea to cut-ready pattern without leaving your bench.
