Under Orders represents a pack of ten cards being shuffled. Each card is represented by a colour. The first column shows the cards in their starting places. The second column shows the positions after one perfect shuffle so that the cards which were in the bottom half of column one alternate with those which were in the top half. The third column shows what happens when the cards in the second column are shuffled again, and so on. After ten perfect shuffles, the cards have returned to their original order, shown in the last column.
A crochet afghan is shown here but the instruction booklet describes how to make an afghan of this design using knitting or crochet.
