The illusion is based on a work by Russian artist Lodygin Sergey Pavlovich, (1893 - 1961).
The image is a very complex drawing of a surreal head and flower. The complexity of the image doesn’t make it any more difficult than any other illusion knitting. It is easy to do because you are only using one colour at a time to knit stripes.
When you look directly at the illusion you only see stripes. When you look from the side you see the image.
It can be knitted in any thickness of yarn. The original is in DK and measures approximately 104 cm x 132 cm (41” x 52”).
The pattern has various versions of the chart, including one intended for mobile devices.
