Pressing pad idea.

 I have a different desk now and needed a different ironing set up. Here is a sleeve that I made to place over a wooden cutting board. There is a layer if Insul-Bright between two layers of fabric. Then I sewed that into a sleeve. 

 The wooden cutting board is a little difficult to see on the wooden desk, but the sleeve slips easily on and off for washing. 

You can see the handle of the cutting board on the left. The cutting board is the best that I have found so far to prevent heat from getting to the desk. It is also thick enough that steam doesn't damage the desk. This is small enough to be portable and works well for my quilt blocks and other smaller projects.
