Label Everything Fragile! Nothing could be worse than your Movers picking up some fine china and throwing it into their truck without knowing what it is.
Let your team know what's breakable and what isn't by simple process of writing it on the box. Movers are paid to be delicate with your valuables, so a good moving team will take care of your stuff. Make sure they know what they need to be careful with, though, because they'll be that much more attentive when taking care of your boxes.
