JDR has some books and they describe them a little for U.S. people they also have Brandie's Video.DVD
I have this book JDR Brazilian Embroidery Book 1 by Ria Ferrell.
The video has much of the same things. what is not in the video By Brandie is explained in the pdf files on the DVD. The only flower Iam not sure of being in there is the carnation.
I have North American Flowers in three dimentional embroidery also and I think you want to try some simpler things first at least that is how I feel.
