20. Don't Make These 4 Stained Glass Design Mistakes!

Don’t Make These 5 Stained Glass Design Mistakes!
Thoughtful design choices can save you time, money and extend the life of your project.

Designing for stained glass is more than creating a beautiful image — it’s about understanding how glass cuts, breaks, and the strength and longevity of the design. Here are four design tips to consider on your next build.

1) Avoid Pieces That Are Too Small, Skinny or Long Pointed Pieces

Skinny glass pieces may seem delicate and elegant, but they are often the most vulnerable parts of your project. Tiny pieces are challenging to cut, grind and are often covered mostly by the metal. Having small pieces means more metal and less light passing through the glass. Let the glass do the talking! 

2) Avoid Crazy Curves or Impossible Cuts

Glass prefers to be cut into simple shapes. Impossible cuts are usually the first pieces to break — either during cutting or later under stress. They can also be extremely difficult for another artist to recreate if your piece ever needs repair in the future. Simplify your lines. Gentle curves and balanced shapes are easier to execute and more durable as your window ages.

3) Avoid Pieces Larger Than 12" When Possible

Most glass retailers sell sheets in 12" x 12" pieces. If a piece in your project exceeds that size, replacement pieces are large and require more glass to replace. Designing with standard glass sizes in mind makes your work more practical, economical, and repair-friendly.

4) Using hard to cut glass for challenging shapes

Not all glass has the same density and this becomes especially important when your design includes tight curves, points, or challenging shapes. Some glass types are notoriously difficult to score and break. When you pair hard-to-cut glass with already challenging shapes, you increase the risk of breakage and wasted material. Choose glass that cuts more easily for complex shapes. Matching the glass to the shape difficulty will make your project more successful from start to finish.

Thoughtful planning today leads to lasting craftsmanship tomorrow.
