Lunarheavenly makes very tiny flowers, sometimes mixed with embroidery work. Some of her books are on the site, in Japanese, and she has more finished works on her insta. xiaoshimei has a YouTube chanel (in chinese) with a lot of different patterns including some of the nicest flowers I've ever seen. I dont understand a word of Chinese, but her videos are petty easy to follow with some written instructions on the screen.
I have these Russian magazines where they take those flowers in different sizes and make dresses and bikinis, and shawls. BEAUTIFUL stuff. You end up with a one-of-a-kind. I'm about to make some shell motifs and use them to cover minor mistakes in a hat. I guess you can use flowers for mistakes, too.
