I had DH build up an old microwave cart to ironing board height (he just added blocks of wood to the top). Then he cut a piece of plywood about 30 x 40. He made a "frame" on the bottom of the plywood to set securely on the blocks on the cart. I covered the plywood with batting & 100% cotton canvas. Sprayed with water bottle & let dry. Canvas is now stretched taught. So now the board is removable in case I need the added space, but will probably leave the board on the cart 95% of the time. Makes it very nice when pressing yardage too!
