The illusion is based on Beata Beatrix, by Dante Gabriel Rossetti. The original painting, which is now in Tate Britain, was dated 1864 but not completed until 1870. Rosetti later created several other versions.
The illusion shown in the photos was made using DK yarns and measures approximately 80 cm x 60 cm (32” x 24”). It used approximately 360 metres (400 yards) of each of two colours plus some extra for the border. Any weight of yarn can be used but other yarns might change the overall size.
When you look at the knitting from directly in front you only see stripes. The picture appears when you look from the side. Photos never do justice to illusion knitting. They have to be seen in real life to get the WOW factor. You can see some videos on the World of Illusion Knitting web site.
The pattern includes large and small charts plus a version for tablets so you can use whichever suits you best.
Steve Plummer and Pat Ashforth are leading experts in illusion knitting, having revolutionised the charting methods to create complex pictures from very simple patterns.
