I really like the felt ball centers! For my things I usually am more literal and prefer something more "realistic" (although I have done covered button centers that end up looking like candy) and I hate that that boxes me in, but felt balls for flower centers are a cute way to add a colorful little pop to your bloom. The source links to a tutorial so please have a clicksy!
Lastly I was struck by the realistic blooms of this japanese hair ornament. Please click on the source to read more about this dying art and a little how-to of how these flowers are made.
Guess I should of called this tutorial flower friday!
