Squares That Look Round Illusion - PDF knitting pattern
Two illusions in one!
The first illusion is created by using the illusion knitting technique so that you see squares when you look from a distance, stripes when you look closer, and circles when you look from an angle.
The second illusion comes from the perception of 25 different shades when the hanging only uses five different yarns. This effect is only seen when the piece is viewed from directly in front.
What you see varies according to the lighting. At times you can also see circles that appear to be embossed on the background. It is very difficult to capture all these effects on camera. The hanging needs to be seen in real-life to appreciate how much it changes.
The hanging in the photos was made using DK yarns and measures approximately 75 cm (30”) square. Any smooth-ish yarns can be used. Using a thicker, or thinner yarn will change the overall size of the hanging. It uses five closely related colours but any five colours will work. They can be toning, or contrasting, depending on the effect you want to achieve.
We do not recommend this pattern for your first illusion knit. It is more difficult than the complex-looking pictures because it uses several balls of yarn at once. You are only ever knitting with one at a time and the rest are left hanging but they may need to be untangled frequently.
Apologies to Roald Dahl for the title. He invented SQUARE SWEETS THAT LOOK ROUND in Charlie and the Chocolate Factory.
