How it works
From photo to cutting table in four steps.
- 1
Drop a photo or a pattern
A photo of your dog, your house or a sketch, or a pattern you already have. JPG, PNG, WebP, SVG or PDF.
- 2
Set the real size
Enter the finished width in inches or centimetres and pick copper foil or lead came. Every check runs at that size.
- 3
Fix what won't cut
Problem spots are marked on the pattern in plain words, each with a one-click fix: add a break line, merge a piece, close a gap.
- 4
Download the packet
A full-size PDF tiled on Letter or A4, a numbered key, a colour key, a glass and foil shopping list, and an SVG for Cricut or plotters.
The cut check
What glass won't do, in plain words.
Every piece is checked at your finished size, after the foil or lead takes its share of each line.
Sharp inside corners
Glass can't turn a corner inward. A V-shaped notch needs a line through it so it becomes two pieces.
Deep inside curves
A deep, narrow bay chips and cracks. It has to be nibbled out with grozing pliers, or split with an extra line.
Pieces inside pieces
A piece completely surrounded by another would need a cut that starts and ends in the middle of the glass. That can't be done.
Slivers, thin necks, tiny pieces
Judged at the final size, after the line width is taken away. Too thin and it snaps; too small and you can't hold it to grind.
Crowded junctions
Too many lines meeting at one point, or junctions bunched too close, make weak spots and messy solder.
Open seams
Lines that stop short of another line. Every line has to run edge to edge, or the piece can't be cut out.
The limits are sensible starting values, not a standard. Pick Beginner, Intermediate or Advanced to make them stricter or looser. They will be tuned with working glass makers. Which cuts are impossible in glass?
Photos never leave your device.
Everything runs in your browser: the pattern, the cut check and the PDF. Nothing is uploaded, so there is nothing for us to keep, lose or look at.
