Skip 2 chain, crochet 5 dc into next chain ( repeat 10 times)

( finish 1 big petal)
{Sl into next st, ch 4, crochet 2 tc into next st ( repeat 3 times), ch 4, sl into next st to join} repeat 9 times.

A finished rose has 18 petals.
Roll the first petal, hold it tight then wrap the next petals around.
Make it abit looser each round, dispart the petals for a better result.
Sew the petals together.
Attach a bead to the center ( I used crystal bead).
