Use furniture drawers to hold delicate items. Wrap them in bubble wrap or newspaper.
When packing toys or smaller objects, remember to fill boxes completely, stuffing open areas with plain newspaper to prevent collapsing when stacked.
Be careful not to store anything combustible (such as paint and chemicals) or perishable (such as food that is not permanently sealed).
When storing lawn and garden equipment, drain any fluids prior to storage in order to avoid corrosive damage.
