These fantastic crocheted brooches by Irina Astratenko keep my interest on them! She just cannot stop finding new crocheting techniques. I did a lot of crocheting at some point... It is really not easy to surprise me with a crochet technique :) However, Irina keeps surprising me!
She has a video tutorial in her blog, so if you are interested to learn how to make this flower, just go there and watch video >>>
