I bought a 2 x 4 x .5 piece of plywood, covered it in 2 layers of cotton batting I had laying around and then added the silver heat resistant fabric I had laying around, stapled it to the back side. Then I marked the underside where it would lay over the regular ironing board and added some metal flange type pieces so it won't move around when laying on top of the ironing board. I can take it off easily to press clothes if necessary and then just lay it back on top which is how it is most times. Best investment I ever made and the only thing I had to purchase was the 2' x 4' x .5 plywood from my local Ace Hardware. They have them already cut to size.
