Start With a List...
Make a list of packing materials needed: boxes, bubble pack, unprinted paper, tape, marking pens, rope, drop cloths, mattress and furniture cloth covers, etc.

Allow Plenty of Time
At least two weeks before moving day, start packing items not used on a daily basis like knickknacks, books, holiday decorations, excess linens, etc.

Boxes
When packing boxes, try to limit each box weight to 30 lbs. Fill each box in such a way that nothing is crushed or compressed.

Fragile Items
Pack fragile items, well-wrapped in bubble wrap or paper, packed tightly but not forced in the box. Cushion each box with crumpled paper, on top, bottom, and between layers. Pack breakables the same way in each box and separate breakables from large, solid, or heavy items.

Label Your Boxes
Label and number each box as you seal it to identify in which room it belongs and mark FRAGILE on all boxes with breakables. Make a reference list as you pack.

Size Matters
Use small boxes for heavy items and large boxes for lighter items. Try to use a box for everything. Odds are, if you move things unboxed, they will be dirty or damaged by the time you need them.

Protect Against Mildew
Never store anything in sealed plastic, especially in non-A/C storage. The humidity will cause mildew which can damage just about anything.

Books
Pack books flat to protect their spines.

Glass and Mirrors
Wrap pictures, mirrors, and glass tops with cushioned paper or moving blankets and crate.

Lamps
Wrap lamp bases in padding. Wrap lampshades and place in separate cartons.

Clothes
Hang clothes loosely in wardrobe boxes. For extra protection, take a square foot of light cheesecloth and fill with cedar chips, tying all four corners together so none of the chips get loose in the box.

Beds
Disassemble bed frames and other furniture when possible. Wrap for protection.
