The best way I have ever been successful in expanding my real estate safely has been to park the wider end against my cutting table or my kitchen counter. I have tried a number of add-ons over my 60+ years of ironing both by the piece (back in the day) and with my quilting. Leaving that inch or so between the counter top and the board allows full use of the board while things like the iron, water bottle, starch, or even interfacing awaiting attachment with an applique are all much safer. I also have space to manage all my cut pieces with ease. I don't think, but I could be wrong, that there is an item available that can without some danger be attached to an Ironing board that will give you more space. Most ironing boards are made to manage a given balance when standing alone.
