Design by Amragul from Crochet/Crosia Home.
This pattern is for the pink flower only. It has a lovely open center with a scalloped edge to give it a realistic look.
And it looks great in a vase, but you might also be able to use it on a hat.
You will need a 4 ply yarn and a 3mm crochet hook to whip this up. For the stem you will also need a soft wire.
