I have a couple of ironing pads that I bought online and when I need to press something really big, I put them on my kitchen table that has a formica top and iron away. Works just fine as I have no room to store a large ironing board.

I had a after remodel door. Wrapped it with W&N and muslin put on top of a metal cart.

I did that and my iron almost fell off. I wasn't looking.

My 22x36 is temporary but right now works for me. DH is wanting his board back. I want my ironing surface!

I too made my board out of plywood - 1/2 inch ply with two 1 inch moulding strips to hold it onto the old metal ironing board. I covered it with a layer of mylar, two layers of warm & natural, and used canvas as my cover. After stapling everything tight, I used a spray bottle of HOT water to shrink the canvas. Worked great. Then I used a straight edge and marked the top (micron pigment pen): three straight lines the length of the board (48inches) and several lines perpendicular so that Icould press/iron my selvege edges straigh (one on the right side of the board and the others at 42, 44, and46 inches. These measurements have sure made ironing yardage a lot easier and finding the straight grain is also a lot easier.

I have an old dresser in the basement and I am planning to convert it into an ironing surface and storage for my sewing room.
I have an old cotton quilted mattress cover with a hole in it, that I will trim to fit the top. I also have an old torn metallic coated table-size ironing pad that I can rescue a piece to cover the mattress pad and top of the dresser.

All I have to do is wait for the snow to go away, so I can move the desk out of my sewing room and the dresser in. No getting it down the basement stairs!
