You can save time and electricity using this one simple trick for ironing. Put a sheet of aluminum foil under your ironing board cover before ironing. The reflected heat and insulation from the foil makes it so you don't have to iron the other side (and totally speeds up your ironing process). You don't have to worry about your ironing board cover scorching, it takes a much higher heat for that.
Using a reflective ironing board cover can cut your ironing time in half. This is a page about making your own reflective ironing board cover.
