I made this flower from the book ‘Crochet Bouquet’, by Suzann Thompson. The flower is called a Columbine. I used left over Noro Taiyo yarn in two colours and a little of another yarn for the stamen in the centre. I bought the hat a little while ago and it did have a flower on it already, but I wanted to make my own flower for it. I took the existing flower off to sew my new one on.
