Travelling lite

This is my suitcase with the flap open. It is from Rick Steves and only measures 21 by 14 by 8" deep. We were determined to go 100% carry-on since we are taking so many flights. The size an weigh were determined by the airline that was the most restrictive.. China Airlines. Max carryon is 11 pounds! The suitcase does not have wheels, but does have a shoulder strap. Three outfits a sweater and light jacket. We are really counting on the laundry service at some of the hotels where we are staying. At this point I don't know if everything will fit in here.
