I am just back from posting some sarongs to a friend who is teaching Indonesian at a very remote country high school (most of the students have never even met an Indonesian person). I suggested she set the students a challenge of trying to work out how to wear the sarong before showing them these instructions. I have asked her to take some photographs of their attempts to show me.
