Travel Tip from a client: Stack all your shirts together, fold in the arms, and then roll them up. The client did this last year for a trip to Europe and said it really worked – it even kept out the wrinkles.
I tried this on our recent summer trip and found that it worked better for synthetic or blend shirts, rather than all cotton ones. My all cotton T-shirts were still pretty wrinkled.
I also tried stacking and rolling all my shorts and skirts together; they didn’t have too many wrinkles and it definitely saved space.
Do you roll your clothes when you pack? What's your packing secret?
