Pattern Sizer: try the cuttability checks live

Pattern Sizer runs the same checks used on every paid pattern, live, in your browser, on the free First Cut Medallion pattern. Pick a panel width between 6 in and 16 in and a cutting technique, foil or lead came, and watch the numbers update: piece count, minimum piece width, minimum interior angle, cutting margin, and glass area per color with a 15 percent waste allowance.

The checks shown here are geometric. They confirm a piece can be cut and fitted at the size shown; they do not replace checking your own glass, tools, or technique.

Every paid pattern in the catalogue runs through the same checks at build time, for the exact size you order.
