Clutter

I recently read Don Aslett's book "Clutters Last Stand". And it really motivated me to get rid of stuff! I did cheat a little and put at least 4 boxes in storage but a lot of that was baby stuff...I wasn't going to get rid of my baby stuff! Anyway Scott and I got rid of two big garbage bags of clothes. And there was a lot other thing we got rid of. However there are two types of items I just couldn't part with: Expensive things and Free things. I know they are the ends of the spectrum but the middle stuff is easier for me. What about you? What can't you part with?
