Do the same for the next petal. Pull the thread to gather the felt at the bottom of the petal. Here's the first two petals pulled together.Continue this process for all 5 of the large petals. Once all five petals are complete, join petal 5 to petal 1. Pull the thread as tight as you want to get the desired amout of gathering. Begin the same process for the smaller petals.
Until all 5 small petals are complete. Here I sticth them down to the large petal base as it makes it a bit easier to work with.
Add the remaining three petals on top of the second layer and secure down.
Choose a button for the center of the flower and stitch to the center of the flower. One your button is in place take the final small petal and cut two vertical slits and a horizontal slit in the felt. This creates a slot to fit in the pin without it showing on the back of the flower.
Glue down the flap to the bottom of the pin.
Then glue the entire pin back to the back of the felt flower.
Voila! Your completed felt flower pin.
