1. Set the finished size first
A detail that looks generous while zoomed in can become only a few millimeters wide on the bench. Enter the intended pattern width and inspect the smallest pieces. Zoom changes your view, not the physical dimensions.
2. Look for enclosed shapes and narrow connections
An enclosed shape may need additional seams connecting it to an outer boundary. A narrow bridge joining two large areas deserves attention because breakage can ruin the entire piece. The editor highlights possible concerns, but the choice of glass, tools and technique still affects what is practical.
3. Simplify without losing the subject
Merge background fragments before removing recognizable features. Bend a shared border to give a narrow piece more room. Avoid adding anchors just to smooth a curve: work with Bézier handles and keep only the structure you need.
4. Compare the proposed repair
Select a cutting concern to inspect its location. Auto fix previews a candidate change; it is not a manufacturing guarantee. Compare the highlighted area before applying, and use Undo if the new seam changes the character of the design.
5. Make a paper check
Print at the intended size and check the pattern with your chosen glassworking method. Allow for the foil or lead system and your cutting process. Consult an experienced maker for uncertain cuts; a software warning or lack of warnings cannot certify fabrication safety.
