Congratulations of the new home.:001_smile:
One great tip is that many places will pick up for free donations if you call and have a lot. And they will give you a tax receipt.
When we have to declutter to move we set up areas to and designate love it, leave it, loose it. Bag, box and place all donations, sell items in closed containers away from those who love them. Bless another with your mess;) but in a good way.
Flylady has a great moving section. http://www.flylady.net/pages/Flying_MovingTips.asp
