Natural coroplast panels zip-tied then taped together into a column. (3 panels per column so each column was 4′Wx24′H) She broke the columns up into triangles with gaff tape, cut up scrunched aluminum screening to fit some of the triangles and added corrrugated aluminum for other triangles. She used orange construction fencing as a stencil and rolled on medium grey paint which created the polka dot look for other triangles. Then she left some blank. Very cool.
