We don't even have an ironing board in the house.
Besides, I never need to iron a whole shirt. The only part that gets wrinkly are the two sides on the front where the buttons and button holes are. Those get all folded over and look bad.
So, what I need is just a little iron in the form of a clip. About the size of a mini stapler. Just to go over the sides, because those are the only parts that need to look good, anyway.
This invention could be small, portable, and even battery-powered. It could fit on your keychain!
