Brazilian embroiery is a type of surface embroidery that uses rayon thread instead of cotton or wool. It is called "Brazilian" embroidery because the use of high-sheen rayon thread in embroidery was first popularized in Brazil, where rayon was widely manufactured. Brazilian embroidery patterns usually include flowers formed using both knotted and cast on stitches. Although many of these stitches are used in other forms of embroidery, the technique used to create them is slightly different.
