The middle row of flowers are made by cutting an approximately 36" x 1" strip of felt, then cutting slits across the one inch side to about 1/4 inch of the end (if you go too far you'll cut it off). At that point, you use a glue gun and glue and roll the felt strip up, and add a clip on the back. You can fluff it out to make it nicer.

The bottom two on the last row, tutorial : http://www.thelittlegiggler.com/2011/06/felt-hibiscustutorial.html The only difference is that I used a hot glue gun instead of sewing.
