You will love yours!
I made one.
It's easy peasy
I took a piece of plywood, cut to the length I wanted and I rounded the corners so they weren't so pokey.
Lay your cotton material (I used stripes cause I had it in canvas and it was fun to look at) that is about 3-4" bigger than your board on each side.
Put 2 thicknesses of cotton batting on that,
Lay your board on that.
Take a staple gun and wrap around the fabric and staple... all the way on one side - then do the other side, stretching the material as you go.
Then do the short ends the same way - pulling, and stretching to get it tight.
I then took pieces of 1x2" boards, cut in to 4 pieces,
Lay your ironing board on top and mark where you should put your cut pieces of wood - I put one on each side of the length of it and one on each side of where the ironing board tapers... then nail them in place.
Bam! You got a kickin' ironing board that other quilters are jealous of! I know that my sewing group loves my ironing board!
