How can I ship large picture frames efficiently and safely?

To ship large picture frames efficiently and safely, follow these steps:

1. Use sturdy cardboard boxes that are slightly larger than the frame to provide extra protection.
2. Wrap the frame in bubble wrap or foam to prevent damage during transit.
3. Secure the frame inside the box with packing peanuts or foam inserts to prevent shifting.
4. Label the box as fragile and mark it as "handle with care" to alert handlers.
5. Consider purchasing insurance for valuable frames in case of damage during shipping.
6. Choose a reliable shipping carrier with experience in handling fragile items.
