For the pictured flower I started from the lower right corner of the block - entered the block then did a loop-de-loop then not quite a straight line to the center to make the little circle that is the center of the flower - then just make petals for as many layers as I have room. That flower has pretty defined petals for the inner ring. Others I've made have the inner ring looking pretty much like the outer rings - maybe more like a camillia than a daisy. It doesn't matter what corner I enter from - depends on what I've done just before.
