The first folding exercises are done with four identical squares of fabric in a solid color, with sides about 12″ long. Each square of fabric features stitched lines in a contrasting color to indicate how it will be folded.
·         Fabric 1: single median line dividing the square into equal rectangles
·         Fabric 2: horizontal and vertical median lines dividing the square into four equal squares
·         Fabric 3: single diagonal line dividing the square into equal triangles
·         Fabric 4: double diagonal lines dividing the square into four equal triangles
As you can see, this exercise is also a remote preparation for geometry! As the child practices folding, she unconsciously absorbs the shapes resulting from the dividing lines.
