I wanted this illusion knit to be another portrait so I spent quite some time trying to find the right subject. Looking for a face that is easily recognisable and shows interesting character is not always as simple as you would think it should be. I think that I have found such a subject though in Albert Einstein.
The illusion is knitted from the side, is approximately square and is about 26 inches (66cm) along a side so is intended to be used as a wall hanging or as the centre of a bed cover.
I used DK yarn and 3mm needles to give a firm fabric in my tight knitting. Larger needles, thicker yarn or less tension would give a completed piece larger than that stated.
One of the photos shows the piece when viewed from directly in front.
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!
