Space Savers! Packing Cubes!
If you don't own a set of packing cubes, then you need to buy a set!
The first time I found out about packing cubes was during a conversation with a friend that mentioned the words "packing cubes" when we were talking about traveling and packing.
And I said, Wait. What? Packing cubes? What's that? When she explained what they were and showed me videos on youtube, I was hooked! I knew I had to get a set of packing cubes. Obviously, the first place I searched was Amazon and the rest was history.
Here's a "how to" video about organizing your clothes in packing cubes. Links to the products I mention on the video are below. Enjoy!
