How to fold clothes in a suitcase with no wrinkles - never iron in a hotel again.

I saw this while surfing the Net today, and I thought it'll make useful info someday. I usually travel with a weekend carry bag with all of my clothes in cylindric shape after I roll them up to save space. When I reach the hotel I'll ring the house keepers for an iron. I'm not sure if this technique will save space in your bag or simply just keeping your clothes with no wrinkles, cause I hate traveling with a big luggage. If you have tried this folding technique, please let me know.
