In order to make Marzipan roses, you must cut a rather thin slice of Marzipan (using the color you want). Smooth the edges of the slices and fold it over to make the center of the rose. Cut another slice, smooth the edges and fold it around the first one. Very easy. Add 2 or 3 petals and add leaves as demonstrated with the green marzipan.
Bon appétit !
