Starch for clothes

You can make your own fabric starch by boiling a couple of tablespoons of rice in a quart of water for a half hour or so, then strain the rice out. Use it warm as it gels when it cools. Pour it into a glass jar to store and just warm it a little when you want to use it again. You'll need to rinse the nozzle of a spray bottle after using it.

Reusing wrapping paper

Did you save wrapping from Christmas gifts? Most papers can be ironed to get the wrinkles out (NOT the plastic or shiny types). If you save the cardboard tubes it came on, wrap it back around them, but if you didn't save the tubes, wrap it around any other paper you have on tubes - or simply roll it gently on itself. Secure it (and all rolled wrapping paper) with a rubber band. You won't waste any because of tape.

Ironing clothes

It's cheaper to iron clothes than to dry them in a dryer. If you can time it, hang them until they're almost dry, but not quite, then take them down and iron right away. If you can't iron at that moment, roll them and put them in a plastic bag until you can get to them. (How long you can leave them there depends on your climate - don't let them mildew.)
