Perhaps you have existing windows that need to have the styles blended? Designing custom leaded glass windows based on existing windows is not a problem. You can place your confidence in the Cavallini Co., Inc.’s team to achieve the harmonious results you expect from your windows while considering many critical variables including: Architectural elements of the structure, congregation’s or organization’s intentions, theologically or logically correct themes, budgets, & deadlines.
