I do the same as Larry said. What I take that needs to hang I have in the garment bag already with a hanger. There is plenty of space and we then hang our jeans and other things on the hangers.
If we are going to wear t-shirts the next day and they have been packed and wrinkled we give them a spray of the wrinkle releaser stuff and hang them in there too.
Kathryn is right about protecting the ends of the wire hangers. We collect the double loop ones that are not sharp and then secure a foam beer Koozie over it
