I have an ironing board called the BIG BOARD. It is just that, a big piece of 1/2″ ply wood size: 22″ x 60″. I have had it for about 10 years. The original cover was in desperate need of replacement. I had one with a grid marks which did come in handy. But, I could not find a new one to fit it. Instead I searched for and bought cotton duck on Amazon. What nice fabric! And, great price: $4.46 yard. It is woven so fine that it is like satin (almost). It would be excellent for stretched canvas to paint on.
Find it here:
I think I will buy some more. It would be perfect to paint interesting effects on and make bags with.
I decided to leave the old cover on which had foam padding.
The board is placed upside down on the canvas. You can see that there are some boards underneath fitted to the size of the table top that hold it in place. I used 3/8″ staples to attach the canvas. The best way to do this is to start in the middle of each side. Staple 3 times at the center of one long side and then the opposite side. Repeat on the short sides. Continue to work out to the ends equally.
