My Daughter and I made this cute little headband and it took all of about 10 minutes. You only need 3 items and a hot glue gun.
I am the queen of looking for tutorials. I googled - DIY felt flowers and there were a bunch of ideas ranging from very simple flowers to very fancy flowers! We went with the simple flower.
Find some fancy ribbon and a plain headband. Wrap your ribbon around the head band and carefully glue the ends down with some hot glue. Make your felt flower, glue it on and you are done!
I did add a small circle of felt to the bottom of the flower to hold it onto the back of the headband.
