The tutorial mentioned here is the way my daughter and I made mine-except I wanted the corners rounded and my daughter cut them for me after we drew the corner using a plate for the rounding. Tried to put it on an ironing board I had purchased and it was too heavy and the whole thing started to go sideways. At the Senior center we found an older, heavy duty ironing board for $1.50 and it stands strong. I can take it apart easily and stand it up to store. Love, love,love my big ironing board. The board I used was in the garage so my expenses were mainly the canvas and batting.
