Having come across the idea of illusion or shadow knitting I decided, being a fan of the Terry Pratchett Discworld series, that Death’s Head would be a very appropriate design to try using this technique.

The completed design is 120 stitches wide and 180 ridges (360 rows) high.

The third and fourth photographs here show the completed design looking directly on the front and directly on the back.

See a video here.

September 2013 Update
The pattern now includes an extra chart intended for tablet users but others may find it helpful. You can view 20 ridges at a time and always be able to see the numbers across the bottom of the chart. Never lose your place again!
