Use sturdy boxes. Fill the box to the brim and seal the lid. That way, you can easily stack boxes on top of one another
Tape the bottom of the box securely so that it doesn't give way
Spread the heavy items over a few boxes. Balance boxes with lighter items like towels or soft toys. Pack the lighter items on top
Use bubble wrap or newspapers when packing fragile items
Mark boxes. Boxes should be marked "Fragile" and "This side up"
Label each box clearly and which room it belongs to. Write on the sides of the box as well
Pack a separate box of essentials you may need for the first night at your new house. Include items like toiletries, toilet paper, bottled water, snacks and a change of clothes in case you cannot unpack everything in time
