Stained glass patterns that check their own cuttability

Most stained glass patterns online are drawn for one fixed size, or generated by an AI image tool that has no idea whether the shapes it drew can actually be cut in glass. Glass Cut Patterns takes a different approach: every pattern here is built from vector geometry, then checked against the same three rules a glass cutter runs into on the bench, at the exact panel size you choose.

Pick a width between the pattern's minimum and maximum, and the pattern is rebuilt for that size before you download it. The checks are computed, not estimated: minimum piece width (at least 3/8 in, since narrower slivers tend to snap during grinding), minimum interior angle (at least 30 degrees, since sharper points are hard to grind cleanly), and reentrant curve radius on any concave cut. Every download includes a full-size tiled outline for transfer, a numbered piece map, a color reference sheet, a cutting-margin pattern for your chosen technique, and a glass and supply list.

Try the free Pattern Sizer tool on the First Cut Medallion pattern, browse individual patterns from $9, or get the Beginner Pack or Complete Collection bundle.

These checks are geometric. They confirm a piece can physically be cut and ground at the size shown; they do not replace testing your own glass, your own tools, or your own cutting technique.
