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.
The final photograph here shows the piece when viewed from directly in front.
