I think this is one of those posts where pictures say more than 1000 words. This was my process for creating a 3D felt flower out of the scraps leftover after creating my first flower from a single piece of thick pre-felt.
This is the base of the flower, upside down, since I’m forming the bottom of the batt.
Lay some scraps on top of the tiny little batt.
Add a little yellow for the stamen.
Put the dowel in the middle, pour hot, soapy water on the middle and load up the bubble wrap.
Wrap up the flower; roll, roll, roll.
Unwrap often to check the progress; pull apart the leaves if they start to stick to each other too much. The petals of this flower look very wispy because I started with such a thin batt.
Stop when it looks finished. I needle felted several flowers and some buds made out of scraps to a long, thin felt rope; then added some freshwater pearls and called it good.
