Too cute! Looks just like I cord and probably a pipe cleaner/chenille stem! Gotta try/improvise this!!!

Black flower - this one is knit but I think you could create a crochet cord, form a loop, sew in the center, repeat for the other 5 loops. Repeat for a second layer with larger loops. Finish off. Add a bundle of beads to the center.
