Pentominoes are shapes made from 5 squares. There are 12 different possible shapes and they are all included in this pretty scarf.

It is also possible to arrange the 12 pentominoes in other rectangles which might be used for a shawl design. They are 4 x 15, 5 x 12 and 6 x 10.

The pattern is also available in Mufflermatics - an ebook of shawls and scarves.
