It has been seven years since I last packed up my house, and this time I had 3 more little humans and all of their belongings to add to the mass. Plus we weren't just moving across town, but across 3 states. I knew I needed a good plan, so I searched and pinned several ideas and kind of mashed them all together to come up with a good system.
Supplies I gathered:
--Boxes: We actually didn't have to buy any boxes. We had a few gracious friends who had recently moved and gave us their broken down boxes! You can also search Craigslist and garage sale sights...sometimes people give them away for free.
--A Good Sharpie
--Duct Tape in different colors
--A notebook (this part was probably overkill, but it made me feel like I had CONTROL of the packing) (yeah, I've got issues).
First thing I did was decided I was going to pack for the house I was moving INTO, not the house I was moving out of. Then I assigned each room in my new house a color and made a rubric in the front of my notebook.
