When creating carvings for public interactive displays, selecting the right wood is crucial for durability, safety, and aesthetic appeal. The best woods for this purpose combine hardness, resistance to wear, and non-toxic properties.

1. Basswood: A top choice for beginners and professionals alike, basswood is soft, easy to carve, and holds fine details well. Its light color and smooth texture make it ideal for painted or stained finishes.

2. Maple: Known for its durability and fine grain, maple is excellent for high-traffic displays. It resists splintering and can withstand frequent handling, though it requires sharp tools due to its density.

3. Walnut: With its rich, dark hue and moderate hardness, walnut adds elegance to interactive pieces. It’s sturdy but carves smoothly, making it suitable for intricate designs.

4. Cedar: Naturally resistant to insects and moisture, cedar is perfect for outdoor displays. Its aromatic scent and reddish tone add sensory appeal, though it’s softer and may dent over time.

5. Oak: A robust option for heavy-use installations, oak’s coarse grain demands experienced carvers but offers unmatched longevity. Avoid red oak for outdoor use, as it’s prone to rot.

Tips for Success:

- Seal finished pieces with non-toxic varnishes to protect against moisture and handling.

- Avoid woods like pine or spruce, which splinter easily and aren’t ideal for public interaction.

- Test woods for allergens if displays will be touched frequently.

By choosing the right wood and proper finishing techniques, your carved interactive displays will remain beautiful and functional for years.
