Hi Wisconsin from Tennessee
Brazilian embroidery is also called Three dimensional Embroidery, it is done with silk thread all different thicknesses from South America.
There is a lot of needle wrapping like in french knots but with 20 to 25 wraps and then placement to create flowers.
I will try to take a picture and put it on my profile for others to see.
Think you could google on the net and see some. Thanks for asking
