Set up a worktable or cover your kitchen or dining room table so that you can do the majority of your packing on it in the upright position. Bending and stooping to pack will wear you out quickly and cause muscle aches. Keep this work area as open as possible to make the packing task easier for you.
Stack each packed box against a wall out of the way after it is sealed shut to await moving day. Keep clear, unobstructed paths in your residence to prevent the possibility of tripping.
