Just to show you what my group did for the exhibition; and the ceiling in Madrid cathedral that was the starting point. I gave all the girls a copy of the strip, with the triangles carefully marked out, and the edges etc. I gave them calico to trace it onto, and freezer paper to make templates, and the two green fabrics, as all the strips had to have the identical triangles. The other half was at their imagination.
