Nieciez - we do the same, mix it up into diff suitcases, just in case.
Now, I want to clarify - Den does pick out what he is taking/wearing, and then brings it to the packing room. I then at that point take over. If I didn't, then everything of his would be Stuffed, wadded, rolled, creased, and just helter-skelter all over the suitcases. I of course, being the perfect one, have a system and our clothing arrives 99.99% wrinkle free. And if there is a wrinkle - Downy Wrinkle Releaser does the trick.
Calgon - yes it sure does and I would love to have some now. Yum!
