When the shawl is worn and someone looks straight at it they will only see vertical stripes. The picture will be revealed as you start to move around. When you are wearing the shawl you will be able to look down and see the Deathly Hallows symbols yourself.
The pattern includes instructions for making the shawl. The design could also be used as a wall-hanging or a panel for an afghan.
The fringe is not essential. The pattern includes instructions for finishing with a plain border to match the top.
This photo shows the shawl before the fringe was added.
