Well, Jane and Ginger, looks like we've hit the jackpot! Thanks, delurked, Greyscale, StyleFan, unfrumpted, fashiontern, Murph11, Sterling, Janet, Marilyn, Jenn, Ryce, chouette22, and Maeve for weighing in.
Cubes seem to have a lot of fans, mostly for keeping things organized. And yes, my suitcase tends to look like it exploded shortly after I open it. Most of my stuff tends to get hung up, so then it doesn't look so bad.
The compression aspect appeals to me. But it looks like some cubes compress more than others? And does compression set wrinkles? Or the opposite?
Most of my travel heretofore has been to my MILs by car, so volume hasn't really been an issue. I really prefer a tighter capsule and fewer pieces to haul and will be doing some plane travel, so it looks like cubes will be in my future.
