Stained Glass Template
Print a full-size stained glass template from 11 of our own designs: a sunburst, a flower, a tulip, a butterfly, a flying dove, a faceted heart, a mountain sunrise, a rose window, an eight-point star, a diamond with a border, and abstract shards you can reshuffle. Every piece is numbered and carries a colour letter, and the colour key lists the pieces in each colour with the glass area they need and the total length of seams to foil or lead. Set the panel size from a 6 in suncatcher to 16 × 20 in or any size up to 1200 mm, the line width for copper foil or lead came, and the cutting allowance: the cutting copy draws every piece apart by exactly what pattern shears remove, so you can cut templates with ordinary scissors. A colouring version prints just the outlines. Big panels split over several sheets with a 10 mm overlap and alignment crosses. Download a PDF on US Letter or A4, a 300 DPI PNG, or SVG files.

How to use a stained glass template
- Choose a design, the panel size and your paper (US Letter or A4).
- Set the line width for copper foil or lead came, the cutting allowance and the glass colours.
- Download the PDF and print at 100% (Actual size); measure the panel on the page to check the scale.
- Keep the full-size pattern whole as your layout guide and cut the cutting copy apart into templates.
- Glue each template to its glass, cut and grind to the line, then lay the pieces out by number and foil or lead them.
What you can use it for
- A first copper-foil suncatcher
- A leaded window or door panel
- Classes and workshops with one pattern for everyone
- Faux stained glass with glass paint or tissue paper
- A colouring page for kids or adults
- Mosaic, fused-glass or quilt layouts

Piece counts are read from the tool at 8 × 10 in; very small slivers are joined to a neighbour, so a few counts change slightly with size. Our tests check that the pieces cover the whole panel with no gaps or overlaps and that every piece has one number.

Sheets have 6.35 mm (1/4 in) clear at the edges. A view is the full-size pattern, the cutting copy or the colouring version; the colour key adds one page.
Line width and cutting allowance
| Setting | Value | What it does |
|---|---|---|
| Line width | 1 to 2 mm | Copper-foil seams on the printed pattern |
| Line width | 3 to 4.5 mm | Shows how a lead came panel will look |
| Allowance | 0.8 mm (1/32 in) | Matches foil pattern shears: neighbours on the cutting copy sit 0.8 mm apart |
| Allowance | 1.6 mm (1/16 in) | Matches lead pattern shears |
| Allowance | None | Cut the pattern copy yourself with pattern shears |
Shear widths vary a little by brand; check what your shears remove and match it. The pattern-shear widths here are the makers’ stated sizes.

Tips before you cut glass
- Print at 100% (Actual size) and measure the panel on the page before cutting.
- Cut the paper templates carefully; a small error in paper becomes a gap in glass.
- Mark the colour letter on each template and keep the grain or texture of the glass running the same way.
- Wear eye protection when cutting and grinding, and follow the instructions with your tools, solder and flux.

Frequently asked questions
How do you use a stained glass template?
Print two parts: the full-size pattern, which stays whole as the layout guide, and the cutting copy, which you cut apart into one template per piece. Stick each template to its glass, score and break along the edge, grind to the line, then lay the pieces on the guide by number and foil or lead them.
What is the cutting allowance?
Between glass pieces there is a seam of copper foil and solder, or the heart of the lead came. Pattern shears cut a thin strip out of the paper to leave room for it: about 1/32 in (0.8 mm) for foil shears and about 1/16 in (1.6 mm) for lead shears. The cutting copy draws each piece smaller by half that width, so ordinary scissors give the same result.
Which line width should I choose?
The line width only changes how the seams look on the printed pattern. Choose a fine line (1 to 2 mm) for copper foil and a wider one (3 to 4.5 mm) to see how a lead came panel will look.
What size can I print?
Any size from 100 to 1200 mm on each side, or a preset from a 6 × 6 in suncatcher to 16 × 20 in. An 8 × 10 in panel fits one US Letter sheet; bigger panels split over several sheets that overlap by 10 mm, with blue crosses to line them up.
How much glass do I need?
The colour key lists the glass area of each colour, worked out from the pieces themselves. On the 8 × 10 in sunburst (41 pieces), the seams add up to 2.5 m between pieces plus 0.91 m round the edge. Buy extra glass for cutting waste and for any piece you need to cut again.
Is it suitable for beginners?
Yes. The diamond, star and sunburst designs are built from simple shapes, and the round designs use gentle curves only. Start with a small panel and fewer colours.
Can I make my own design?
Pick Abstract Shards and press New layout for a fresh arrangement of straight cuts, change any colour, or download the SVG and edit it in a vector app.
Is this the same as the Voronoi Generator?
No. The Voronoi Generator fills a frame with random cells or takes colours from a photo. This template prints designed motifs such as a sun, flower, bird or heart, with a cutting copy, a colouring version and multi-sheet printing at full size.
Is it free?
Yes. There is no sign-up, no watermark and no limit.
Is anything uploaded?
No. The pattern is drawn by JavaScript in your browser and nothing leaves your device. Nothing is saved when you close the page.
