Tools: A crochet needle. (I used no.7 as it is the only one I have right now.)
Materials: A black crochet lace yarn. (I doubled the strings to give it a bolder look.)
A button for the clasp
Few beads
Process:
Follow the link for a detailed tutorial. The beads part is my own addition. Simply put a bead on each crochet point. Push the bead downward so that it won't look that shabby; plus, it also gives a nice petal effect.
