Good find on the flowers. I think that they are cute and small. These type of flowers seem to be popular right now especially w/ crystals in the center.
I like add felt to the back of my headbands and flowers too. I think that it looks a bit more finished. I just have the hardest time though cutting nice circles. I am a bit a of a perfectionist. I'd love to have a machine cut them for be but I am sure that the machine would be super pricey.
