I wondered that as I folded sheets that I forgot about in the dryer for 2 days and now look like a 3D relief map of the Alps! My mom had an ironing machine back in the 60's for ironing sheets, it was like 2 big 3 foot rollers that heated up. I figure after we sleep on them once or twice they will be wrinkled even more so I won't worry too much.
