It is another "copy cat idea" I think because Rebecca Wat published a book called "Fantastic Fabric Folding" c1960, C&T Publishers, Lafayette, CA. And it includes this idea along with others. I made a couple of the pattern you are talking about...would not recommend it for a child, unless it is a wall hanging...something cute, bright, and lovely for a young child's wall. And easier and quicker than a quilt. Might want to consider that for the child.
