Oh, so sorry . I have the opposite issue in that my husband cannot do anything handy -- it takes three trips to hardware store just to change light bulb. My suggestion, do you know any other handy gentlemen in the area? If not, just purchase one on-line. Mine was made by someone who sold them in a LQS when I lived in Texas. Very simple design. Large piece of wood, shirting strips all around bottom side and then moveable latches that you turn to hold it down to ironing board. And, your husband is right, it's not the sturdiest/steadiest but it's never fallen over either. It is bulky but can easily be removed and stored separately from ironing board.
Good luck in getting one. They are well worth it to iron large pieces of fabric and large quilt tops.
