Get a GOOD heavy duty paper shredder. Take the bills, the duplicate cheques, the duplicate orders... from 1999 -2004. Shred. (took about 3 days, letting the shredder cool down when it quit in a fit of pique and a very hot odour) use the shredded documents as padding for the really delicate "good stuff" crystal and figurines.
Get Space Bags as well as good sturdy plastic bins. space bags are hard to put in the truck so put the bags in the bins. Remember, (unlike this twit "speaking" to you) that even though the bags LOOK small, put enough of them in a bin, the bin is HEAVY!
Make sure your Thrift Shop takes everything else... and keep really careful records of what you donate. (and no shopping while you are in there, although if you DO find that perfect little black dress....what the DH doesn't know won't hurt, right?)
Before you decide to use PODS, make sure they come to your area. We are going to have to either beg for one to come this way, or use UHaul... Best laid plans etc etc.
Ok, that's it so far. As I remember more of my long lost packing skills (Haven't PCSed in a long time) I'll put it down. But if any of YOU have any hints, for heavens sake, let me know.
