The quilt is composed of Heart Modules (video instructions here), and Flower Modules. The Flower Module is a variation of the Heart Module. I haven't made instructions of the Flower Module yet, but they are easy to figure out, just fold the four quarters of the paper in the same way as the bottom quarters of the Heart Module. They connect with each other in a similar way.
I folded the quilt with 4 ½"(112 mm) and 2 ¼"(56 mm) squares, that I cut to size from 9" (225 mm) Pacon Paper Squares.
Happy Valentine's Day!
