You can buy stamens (they come in many colours and shapes) cut them to the size you want and poke them into blobs of icing for the flower centres. Easy Peasy
I make Jewellery (when time allows), I started off working with seed beads and have some large pieces that incorporate Swarovski crystals moving onto working more with larger stones. This is a piece that I designed and made after finding the sterling silver focal pieces on an American website. It's made with semi precious stones, pearls and hill tribe silver. All in all over 100 hours worth of work. I occasionally get it out and wear it.
