Honestly, what a lifesaver.
$10 at TJ Maxx, but can be found at most craft stores.
A jewelry and make-up organizer. It has zippers on every pocket, and 2 sides. I decided to put makeup on one side and jewelry/ hair accessories on the other. Now my necklaces will look like necklaces when I get to Chile, and not be a tangled mess.
I think I might always use this, not just on my mission. TOTALLY Serious.
