Mat Cutting Tips
- 45° bevel: Current angle for mat window cuts (45° is standard)
- Weighted bottom: Traditional technique to prevent "falling" look
- Double/Triple mats: Use contrasting colors for visual depth
- Minimum border: 50.8 mm recommended for most artwork
- Acid-free: Always use archival mat board for valuable art
- Blade offset: For hand-cutting at 45°, offset blade by 1.6 mm
