Started one very similar several yrs ago ( golly, wonder where it is?)... Anyway, it was circles sewn onto fusible web, flipped right side out, set onto a background square, curves overlapping a bit, ironed, then machine blanket switched around those "petals"... That's all I remmber about the instructions...must have been in a quilting mag..don't know which one...
great that you have a finished one...mine will probably end up at goodwill or the curb!----
