For this sock pattern, named after

Bridget Riley’s work, the lines are
formed by a ribbing pattern of twisted
stitches (1 X 1 cables) and purled stitches comprised of an intriguing arrangement of tiny
cables. A vertical mirrored pattern
for right and left socks accentuates
the flicker effect. Moreover, the
socks look different, depending on the
direction from which you view them.
