Ooooh packing! We closed on our house the end of June but I still had 3 months left on my apartment and we couldn't move in right away anyway. It took a while to pack everything and towards the end it got really hard- I would wander around looking for something that would fit in that empty spot I had in the box I was working on... just wandering around like "hmmm what can I fit in here!?"
Even worse- Chad & I weren't living together yet so he had to pack his own stuff- he did a HORRIBLE job!! Every box had the most random things in it and he didn't go through and purge all the garbage and things he didn't need- just moved it all to the new house! So then when I unpacked I had to have a garbage bag right there with me- I threw away candy wrappers, receipts that the print had worn off of, and all kinds of crap!
One thing I did that I was glad I thought of- to pack up my fragiles I wrapped them in seasonal clothes I wasn't wearing at the time rather than bubble wrap or newspaper- I had a lot less garbage when I was unpacking plus less clothes to move all at once!
Good luck- just wait until you have to start UNpacking everything!
