Prpts don't replace the binding. They are an addition to the quilt and the binding is attached after the Prpts.
PrPts are really easy. Try on a sample before doing the baby quilt. The binding is no harder to do with or without PrPts.
Enjoy them.

EDIT: I have never made them using this method. I just cut and fold the squares and slip them next to each other with whatever spacing I need to make them fit. It is more casual. and IMHO, less work that cuting and folding a strip of points.
