See PDF diagrams for how to fold and cut an octagon from a square.
This brooch has a folding sequence similar to Brooch 2 From a Regular Hexagon, with, of course, two more points. As we add sides, the central flower becomes more compact and the profile of the outer star becomes more shallow. The method for cutting an octagon outlined here is the easiest I have seen. —J.R.
