Cut strip or strips about 1 1/2 inches wide, total length of strips should be 30 inches or more. Any direction is fine, if cut diagonally the edge will be more curly. Use the rolled hem setting on a serger and serge one edge. Cut a felt circle about 1 3/4 to 2 inches in diameter.
Gather using a small hand stitch or gather by machine.
The fullness of the flower is determined by how tightly you gather.
Handstitch the strip to the felt circle starting at the outer edge and working towards the center in a spiral. You can do this by machine as well.
It helps to have the end tightly gathered for the center. If the center is messy then you can add something larger for the center like little bit of tulle or larger beads and decorations.
