Hi! Long time reader, first time poster! I've been busy gathering up loads of info here behind the scenes and am popping up now with a light-packing inquiry.
Essentially I'm hoping this thread can perhaps serve as a master list of all the random non-clothing miscellany that you light packers DO include and bring along in your travels. I know I'd benefit from hearing everything on your packing lists from the fun ideas (hobbies etc) to the utilitarian/practical (laundry, hygiene, room supplies, etc) that can actually fit right in with light packing.
I'm inspired to post and ask this question because light(ish) packing hasn't been too much of a challenge for us thus far (because our careers have kept us limited to shorter/closer trips), but as we begin to see a light on the horizon, I very much want us to stick with carry-on only even for longer trips abroad. Whether that's our usual 21" spinners or -- ambitiously -- a backpack + personal item, I want to get a better sense of what's possible!
