Don't make the same mistakes other movers do. Don't think that left over boxes will suffice in packing your valuables and possessions. Since you are talking about your priceless stuff, you have to face the costs of all the expenses and have a budget for your entire move. Packing materials are needed when you move and boxes are highly important. You have to have enough supply of boxes of different sizes and those that are sturdy enough to hold valuables, breakables and fragile items. Also, it would not suffice to just have the supply. You have to know how to packing everything as well inside the box. What is the proper position of the item? And didn't you know that you have to wrap your breakables and fragile belongings first before you place them in the box? Bubble wraps and newspaper are the perfect picks. In moving you have to expect the unexpected because during transportation there is a tendency that your boxes will bust open. Thus, you have to include in your supply too the packing tape. If you place your things in strong box and pack it with equally strong tape, then your possession is deeply protected and you will have fewer worries to think about as your things are intact.
