Look at the knitted picture from directly in front and you will see only stripes. Look at it from the side and you will see an illusion of Leonardo da Vinci's Lady with an Ermine.
Although Lady with an Ermine is not as well-known as Mona Lisa, many consider her to be Leonardo's best portrait.
The knitted panel could be used as a wall-hanging, or part of a bed-covering. The pattern includes information to help you understand how illusion knitting works. It has charts in various sizes, including one specially for tablet use, so you can use whichever you find most convenient.
The panel is 270 stitches wide. The finished size will depend on the yarn you choose and how tightly you knit. The version shown measures about 114 cm by 86 cm.
Illusion knitting (which is also known as shadow knitting) is very easy though it requires concentration and accurate counting. It uses one yarn at a time and only basic knit and purl stitches.
Steve Plummer and Pat Ashforth are world experts in Illusion Knitting and have devised a way of charting illusion knits to allow far more complicated-looking designs than was previously possible.These complex designs are no more difficult to knit than the most basic illusion shapes.
