Packing Breakable Items
There's no surefire way to keep everything safe in a move. Some items are at higher risk, and they should be packaged with more attention to detail to help ensure they come through without suffering damage.
Packaging is key with breakable items. Padding should be used to keep them from contacting other items. There are many products available that are designed for specific items.
The main issues with breakable items will be crushing, pressure points, and contact with other items. If you can prevent these issues, your items will much more likely survive without damage to your new home.
