packing yet again. i need my checked bag to be under 50 pounds and my carry on to be under 15 =/

I'm a bit crazy... saturday i left Oxford. i've been living out of my suitcase while staying in Horsham. i fly out tomorrow and will be in Seattle by 7.15 pst. the next morning, I repack my suitcase for our church's 5 day camping trip. so I'll be living out of my suitcase for nearly another week... but it is all good =)

please leave packing tips as a comment below, especially if you know how to pack fragile, old books into a tightly packed suitcase =)
