In this paper, the authors interlace the work they have been developing in the last years, namely the classification of the Portuguese pavement patterns in the Azores islands (Teixeira, 2015; Teixeira, Costa & Moniz, 2015), with the exploration of symmetries in patchwork and ceramics within a set of professional development courses for mathematics teachers held in Aveiro, in the north of mainland Portugal (Hall, 2016). This paper focuses on rosette groups which in spite of being the simplest symmetry groups with only rotational and/or reflection symmetries, are rich enough to describe an endless variety of patterns/designs found in practice.
