Most people know that to save space in your suitcase, you roll your clothing.  If you didn't know that, well, now you do!

I found when I would go searching through my suitcase to find a particular top, I would pull things out and they would become unrolled.. And if you're in a hurry, this leaves a mess of a suitcase.  When traveling, I want to try and remain organized, despite living out of a suitcase.
So, here is a solution I tried and really like.
I went to a dollar store and bought hair ties and rubber bands.  Cheap ones- No need to spend lots of money!
I used them to wrap around my rolled clothing to keep them rolled up and tight.  Now when I pull things out, the stay rolled and I can neatly stack them right back in!  Plus, I have hair ties and rubber bands around, which surprisingly comes in handy,
And it helps keep dirty clothes separate.  Anything not wrapped in the tie or band is dirty.
