I have a craft table that Michael's sells. It has an electrical outlet on it. I place a double layer of insul-brite on it, then cover with folded fabric. This is my ironing table. When I need to cut, I take the fabric off and put the cutting mats on. :D
I had my dh cut a piece of pegboard to place over the craft inserts (think holes to put cups in for paints) and I place my iron on that, with a silicon base for when the iron is hot.
Very convenient and good surface size.
