This post is for children. Should you find yourself with a house full of children I suggest this fun time activity. They will need their usual art supplies, plus card stock, lots of that to draw and cut and experiment with undisciplined abandon, the usual, scissors, glue, coloring pencils, pens, or crayons, regular child's imagination. The post is lengthy with photos in an attempt to avoid words.
The idea is concentric bands that stand up. They must be made. When the paper bands are folded in half lengthwise then the length of the smashed band must fit the shortest dimension of the card.
The paper bands are divided in three for six equal sections each to make a hexagram. I'm using a string instead of measuring.
