No ,I just wrapped cotton batting around a piece of plywood-works great.

...just wondering if instead of buying insulbrite would a layer of aluminum foil work as well???????

I just want to tell you, The only dumb question is, The one you don't ask.

Two layers of Insul-brite and outside cover of silver ironing board material.

Yes, I covered a large board my husband made with a layer of insulbrite and then a layer of cotton batting. I like a firm pressing surface. Works out great!

You can also get insulated batting that doesn't have the silver coating on it. That's what I used in my holiday tablecloth.

It's not a dumb question at all, it's a very good one. Look at all the replies its generated. Lots of ideas for us to try.

I did use insulbrite and I love it!

I just use a plain ole ironing board, buy a new cover every now and then.
