Illusion knitting is a fun way to show off with stripes. From the front your knitting will look like simple thin stripes, but when you view your knitting at a sideways angle, from the cast-on or cast-off edge, the garter ridges stand out and reveal the hidden pattern. For this cushion design I’ve chosen a dark grey and pale blue for a high contrast.
