This year's Culture Club

I love flower arranging and didn't know how mathematical it was until I took it with my students a few years ago.  This year again my Culture Club is Ikebana- flower arrangement.  I usually put the flowers on Tuesdays in a vase and display them in the entrance way at school but it has been so hot lately that last week I brought the flowers home to put into a vase.  No Ikebana here....
